An only child of working class parents, Sir Derek Jacobi was just 10 years old when he sat down to write a letter that wasn鈥檛 to change his life.

But the twists of fate since that day suggest he鈥檚 a man who has very much made his own luck.

And enjoyed every single minute of it.

Born on October 22, 1938, the young Jacobi was fascinated by the emergence of children鈥檚 programmes on television, so he wrote to Ealing Studios鈥 boss Sir Michael Balcon to see if he had any work for him.

鈥淚 got a reply from his secretary,鈥 chuckles Derek. 鈥淚t said something like 鈥榃hen you are a bit older, contact us again鈥.鈥

Somehow, Jacobi鈥檚 career wheels were set in motion 鈥 to the point he could now perhaps be acclaimed as being the greatest living theatre actor to have come out of Birmingham.

Balcon was born in Birmingham in 1896, gave Alfred Hitchcock his first directing job in 1925 and was the grandfather of Daniel Day-Lewis.

Like Hitchcock, Jacobi was born in Leytonstone.

Mother, Daisy, worked in a drapery store and his father, Alfred George, was a tobacconist.

Jacobi arrived in Birmingham in 1960, fresh from a grammar school education and history degree at Cambridge University, where fellow students included Ian McKellen, David Frost and Trevor Nunn.

For three years, Jacobi learned his craft on the boards of Birmingham Rep in Station Street, following in the footsteps of city-born Paul Scofield, Ralph Richardson and Albert Finney. But it was another Rep old boy, Laurence Olivier, who was to change his life in 1963.

When he came calling, Olivier had already spent two years at the Rep from 1926.

Olivier had also won the best actor Oscar in 1949 for Hamlet (en route to nine best actor Oscar nominations, a record still shared with Spencer Tracy).

Jacobi, in total contrast, had just been rejected by the RSC.

Yet months later, he was under Olivier鈥檚 wing 鈥 and spent his 25th birthday making his first night appearance in Hamlet, playing Laertes opposite the newly Oscar-nominated Lawrence of Arabia star Peter O鈥橳oole.

Jacobi readily admits that career breaks don鈥檛 come much better than that.

鈥淥ut of all the Reps, Birmingham was the most traditional and classically-based,鈥 says Derek.

鈥淎nd I knew it was only 20-odd miles from Stratford, a natural progression for anyone with aspirations for the classics.

鈥淚 Ieft the Rep after Peter Hall offered me parts and a season at the RSC.

鈥淏ut at an audition for Ariel in The Tempest, I hadn鈥檛 been prepared.

鈥淚 read it, but not very well and the response was along the lines of: 鈥楧on鈥檛 call us, we鈥檒l call you鈥.

鈥淚 received a letter saying I wasn鈥檛 鈥楻SC stuff at the moment鈥, so I had to go back to the Rep and ask for my job back.

鈥淚t was 1963 and the 50th anniversary of the 1913 founding of the Rep (which celebrated its centenary last month).

鈥淲e began to do three Shakespeares they had never done, Henry VIII, Troilus and Cressida and Titus Andronicus.

鈥淥livier came to see me in Henry VIII in the spring season and I went from there to his Chichester Festival Theatre and on to the original National Theatre at the Old Vic, spending eight years together.鈥

Could he see at the time what that really meant 鈥 or is it only with the benefit of hindsight?

鈥淥h, I knew at the time I was lucky,鈥 he laughs.

鈥淚 hadn鈥檛 even been to drama school.

鈥淭hree years in Birmingham. Eight at the Vic with people like Maggie Smith...

鈥淭hat鈥檚 11 years of never having to wait tables, so I was really blessed! It was amazing. My heroes are theatre actors and I鈥檝e got to work with most of them.

鈥淭heatre is magic, electrifying, and better than anything I have ever done in front of a camera.鈥

Today, Jacobi is a multi-disciplinarian and a household name 鈥 a 鈥榯ownie鈥 who loves going away and returning to London even more.

His TV credits include I, Claudius (1976, alongside Patrick Stewart, John Hurt, Brian Blessed, George Baker, David Robb and Birmingham鈥檚 own Kevin McNally); Cadfael (1994-96) and his recent hit Last Tango in Halifax (a second run will shoot with co-star Anne Reid this summer). Films range from The Day of the Jackal (1973) to Henry V (1989), Gladiator (2000), Gosford Park (2001), The Gathering Storm (2002) and the multi-Oscar winning The King鈥檚 Speech (2010).

Despite the respective attractions of the RSC and the West End, Jacobi loves nothing better than being in a hit Broadway show 鈥 even though his first run there was cut short.

Three weeks after seeing his debut, mother Daisy died aged just 70 after suffering a brain haemorrhage back at home.

鈥淚 brought them over to New York, and they thought they were on the moon,鈥 he smiles.

鈥淎fter I was born they鈥檇 saved ten bob a week 鈥 and bought me a red Ford Popular for my 21st birthday.鈥

His father lived to be 90 and accompanied Jacobi on the day he received his knighthood for services to drama in 1994.

It was only at the age of 72 that Jacobi felt he was old enough to follow Hamlet with King Lear.

鈥淭wo years ago... how time flies,鈥 he muses.

鈥淚鈥檓 a serf in movies. My great love is the theatre, so that鈥檚 where I flourish.

鈥淲e were doing eight shows a week in London, went on tour and then did seven weeks in New York, so that鈥檚 150 Lears!

鈥淚t鈥檚 a wonderful role, but physically tiring and vocally very tiring.

鈥淵ou wake up every day and think: 鈥業s the voice still there?鈥欌

Such roles are all-consuming at the time, requiring concentration for five hours before curtain up at 7.30pm when Jacobi says: 鈥淚 have to be at the peak of my energies鈥. Age has made him more nervous beforehand, meals can only be eaten afterwards.

But he still finds the buzz of a live audience the greatest thrill of all, at least until someone鈥檚 phone goes off.

鈥淭hat鈥檚 the problem with intervals,鈥 he says. 鈥淭here are notices before but then people turn them on and forget.

鈥淚 haven鈥檛 got the courage to shout 鈥楽hut the **** up!鈥 The manners of an audience have changed enormously.鈥

Another thing which makes him angry is how some people who benefited from the grammar school system like he did then 鈥減ulled up the ladder鈥 to prevent others from following suit.

And then there鈥檚 the failure of some critics to 鈥渞ecognise just how good Kenneth Branagh is鈥.

Having once been labelled 鈥渢he new Olivier鈥, Jacobi agrees that Branagh, now 52, has been under-appreciated despite his five Oscar nominations covering acting, writing and directing.

鈥淢y admiration for Ken knows no bounds,鈥 he says. 鈥淗e鈥檚 a brilliant, natural theatre actor who is great on stage but who loves film, too. He directs, he acts and is one of the most important people we have 鈥 a mover and shaker, a throwback to the old actor/manager which Olivier was.

鈥淭he problem he鈥檚 had is that in England his talent was seen as precocious, like 鈥榃ho does he think he is?鈥

鈥淩ather than accept that talent and go with it and give it its head... he鈥檚 still, strangely, having to live it down that he published an autobiography which was to raise money for his Renaissance Theatre Company.

鈥淭hose critics have been incredibly ungenerous as far as Ken goes.鈥

While many people have trouble getting into Shakespeare, Jacobi has a near-photographic memory to remember texts.

But he worries about the way they are taught.

鈥淭he plays were written to be performed, not examined,鈥 he sighs.

鈥淥ur problem, as the actor, is to think: 鈥榃hat do the words mean? How do we say them? Why do we say them? And to make them accessible, by sounding as if it鈥檚 the way we talk every day鈥.

鈥淎udiences will then understand what you are saying without hearing every word.鈥

The most Jacobi can remember not working for is about four months 鈥 which puts him at odds with Daniel Day-Lewis鈥檚 preference for making films so rarely.

鈥淗e has an admirable reputation for thinking himself into a role, I鈥檓 surprised he didn鈥檛 experience being shot in the head to play Lincoln,鈥 laughs Derek.

Does Day-Lewis deserve his three best actor Oscars, though?

鈥淚n screen terms, certainly,鈥 says Derek. 鈥淗e鈥檚 given wonderful performances.鈥

Jacobi is today still only the second president of Birmingham鈥檚 Hall Green Little Theatre (1950) 鈥 after Olivier before him 鈥 and he expects Day-Lewis to be offered a knighthood soon.

鈥淵ou get two boxes 鈥 yes or no,鈥 he explains.

鈥淚 thought long and hard about it and then ticked 鈥榊es鈥.

鈥淚t鈥檚 strange and lovely and I鈥檓 very proud, but I don鈥檛 really use it. People call me Derek.鈥

Rare is the time he ever watches himself on screen, even though he acknowledges others learn their craft that way.

鈥淚 can鈥檛 be objective enough, I鈥檓 totally subjective. I only watched I, Claudius five years after it was finished.鈥

But one recorded performance Jacobi is proud of can be seen on the silver screen again on Sunday night as part of The Borderlines Film Festival.

He plays painter Francis Bacon in Love is The Devil (1998), an 18-rated art house film which saw him sharing a bed with a burglar played by a future James Bond star, Daniel Craig.

鈥淎nne Reid told me she鈥檇 been in bed with Daniel in The Mother,鈥 Jacobi laughs. 鈥淚 told her I鈥檇 been in bed with him twice in Love is the Devil!鈥

Only this week, Jacobi has just completed filming the final episode of Vicious, a new ITV1 sitcom about two ageing gay men who have lived together for 48 years.

鈥淚t ain鈥檛 King Lear,鈥 he says of the new six-part series co-starring Sir Ian McKellen, another theatre legend with two Oscar nominations to his name.

It will begin on TV on April 29, but in the meantime Jacobi will continue to dream of being offered the chance to meet Daniel Craig on screen again... this time opposite his James Bond persona.

鈥淏addies and victims,鈥 smiles Jacobi. 鈥淭hose are the best parts.

鈥淎nd Daniel Craig is the real deal. A proper actor.鈥
