With roles in Strumpet City, The Irish RM, Brookside and Fair City, acting has taken Bryan Murray to stages and screens all over the world.
This week, however, he is back where it all began, more than five decades ago, at the Peacock Theatre in Dublin, and said his return to the stage is "like coming home".
Murray is starring in a new play, An Old Song, Half Forgotten, which tells the story of a performer, who now has Alzheimer's, who is thinking back over his career.
It is a very emotional piece, all the more so because Murray himself is living with Alzheimer's.
The story of how the drama came about is as moving as the piece itself.
When Bryan received his diagnosis, he and his partner Una Crawford O'Brien were touring with a play called Halcyon Days, written by Deirdre Kinahan.
They called Kinahan to tell her Bryan would have to drop out and the writer says her heart "broke" when she got the call.
"Fifty years," he told her. "Fifty years on stage Dee and I'll never be on stage again."
But Kinahan was determined that would not be the case, saying that surely if Bryan retained his extraordinary talent and his ability to hold a stage, then she could write him something.
What followed is what she described as "an extraordinary journey" to bring this play to life.
The play stars Bryan as actor James O'Brien, and Matthew Malone as 'younger James’.
Off-stage, meanwhile, is a third actor, Darragh Feehely, who reads Bryan's lines to him through an earpiece - lines that he then delivers seamlessly seconds later.
The fluidity of the performance is a testament to the talent of all three actors, and Murray's experience and ability to own the stage shine through.
Murray himself said performing in the play is a "joy".
"I was hopeful," he said, "that it would be OK because I didn't want to give it all up, I was determined that we would find a way."
He also paid tribute to his partner, Una, who has been by his side throughout the whole process, saying her support had been "exceptional".
Crawford O'Brien described watching the play as both exciting and nerve-wracking.
"Every day is a new day for Bryan, every time he comes in, it's a new performance. He doesn't remember last night, so you have to remember that."
Bryan's co-star Matthew Malone, who has been working on the play for almost a year, described the production as "authentic and new".
As well as acting alongside Bryan, he is responsible for guiding him on stage.
He said the show requires a lot of flexibility, and things inevitably go wrong on occasion, but this has become part of the process.
"We've learned that that mistake is actually a texture of the show and his performance. That is genuinely authentic and new every night, so it requires a lot of flexibility from us.
"That, I think, is what experimental theatre is about. It's about experimenting and pushing boundaries."
Certain adaptations have been made to the theatre for the show, including increased signage and name tags for all of the crew. It is an intricate, complex production, but Matthew Malone pointed out it's one that is led by, rather than being about, Bryan Murray.
"He's still Bryan Murray, you know, theatre, TV, film star. Bryan's career is extraordinary. And I may have more cognitive flexibility than he does, but Bryan has a lot more time on stage than I do.
"He is a more seasoned actor than most people around, so his instincts and his skill come alive. He's our senior actor, so I'm learning a lot from Bryan in loads of ways."
An Old Song, Half Forgotten is an Abbey and SoFFt Productions co-production, written by Deirdre Kinahan and directed by Louise Lowe.
