Sir Ian McKellen has spoken of how regional theatre in Lancashire helped nurture a "passion for acting which has never faded" as he prepares to embark on an 80-date tour of the United Kingdom.
The actor will celebrate turning 80 in May next year with a tour of theatres in major cities like Liverpool and Manchester as well as lesser known spaces in Orkney and Lyme Regis.
Profits and his wage from his show, Ian McKellen On Stage, will go to the theatre, with the actor suggesting each space spend the money on whatever it needs, "whether it's painting the dressing rooms or putting in new seats or supporting youth groups".
Speaking to the Press Association, the 79-year-old star stressed the importance of local theatre companies, saying "the more theatre there is up and down the country, on tour or locally, the happier people will be".
He said: "As a theatre-mad lad in Lancashire, I used to see the travelling Century Theatre, which ended up permanently on Derwentwater.
Sir Ian, who was born in Bolton, Greater Manchester, said watching regional theatre had given him his first taste of the stage.
He added that he saw no reason why some parts of the country should remain under-served while larger cities and London receive the best productions.
He said: "If I had had to have been dependent, when I was a boy, simply on a lot of wonderful theatre in London I would never have seen any theatre at all.
"I've never understood why if you live in Lancaster you shouldn't have access to the best theatre going.
"I think it's a pity if theatre becomes only something you do on high days and holidays, and spend a fortune seeing the long-running musical.
"If that's all the theatre-going you do then you are missing out. The more theatre there is up and down the country, on tour or locally, the happier people will be.
"The best way an actor can support regional theatre is by going to work in it."
Sir Ian, who was knighted in 1991, is best known for playing Shakespearean roles and as Gandalf in the Lord Of The Rings film series.
He will begin his tour on January 25 next year at The Space on the Isle of Dogs. The London stretch of the tour will take in the National Theatre and the LGBT-forward Above The Stag Theatre.
He will also perform at venues with which he has personal connections, including the Belgrade Theatre in Coventry, where he first took to the stage in a production of A Man For All Seasons.
His act will encompass his wide-ranging career and include anecdotes, acting and audience participation.
He said: "They will expect to see Gandalf, they will. They probably will expect Shakespeare, and there will be a lot of that. There will be other stuff which will perhaps be more surprising.
"There will be a chance for me to tell a story or two and it will be different perhaps in each place I go to because my memories of the Edinburgh Festival will not be appropriate when playing in Aberystwyth."
Cheap tickets will be available at each show and Sir Ian said he hoped young people would be in the audience at every stop.
Asked what advice he would give to those young actors, he replied: "I advise them to do what I do and go watch other people acting, whether it is stage or on telly or on film, or even on the Tube, or walking down the street.
"Everyone is always acting. All the world's a stage and all the men and women merely players.
"You can learn an awful lot by observing and trying to work out why someone is good on stage and why someone else is not. You can do it for free."
Ian McKellen On Stage will tour from January 25 to September 15 next year.
