After filming wrapped up, Evans headed back to New York where he starred as Dr Frank-N-Furter in the Broadway revival of The Rocky Horror Show.

“I did the show for seven months and I was coming to the end of the run – I had such an incredible experience doing the show,” he said.

“It was just the most wonderful, inclusive, joyous two hours of my day. It was wonderful. The audience were just loving it.”

Evans said that actor Tim Curry had been a part of his “whole journey”, and that he would have people on the stage door and messages “comparing me” to him, and “how proud he would be of the performance.”

Curry, who died in August, aged 80, first played the role on stage before the film version, which was released in 1975 and has remained a cult favourite.

Evans added: “So I had to send him a letter, even if he’ll never read it.

“I just felt like I had to say thank you because I really believe that if it wasn’t for Tim’s performances as Frank-N-Furter, I don’t think that film would still be around.

“He really kept that show, and the messages throughout the show are so prevalent and strong and important today as they were 53 years ago.”

He received a response from Curry’s team three weeks before his final performance, saying that he was “very appreciative” of that letter and thanked him for sending it.

“Sadly he passed the day after I finished,” Evans said.
