Holland, who is set to play the debonair dancer in an upcoming biopic, revealed he’s already started rehearsing for the film.

“As soon as I finish with these tours, I’m diving back into the dance studio,” he told “Good Morning America’s” George Stephanopoulos. “I did my first few rehearsals recently, and it both filled me with excitement and absolute dread because I’ve got so much work to do to to try and do Fred proud.”

In an interview on “Live With Kelly and Mark,” Holland expanded on the project, saying that having “The Odyssey” and “Brand New Day” come out within weeks of each other felt like he had closed the chapter on the first act in his career and is now ready to move into more mature roles. “And what I’m looking for in this next chapter is like the ultimate challenge, and to find things that really scare me,” he explained.

Holland is no stranger to an arabesque, having famously got his big break in “Billy Elliott the Musical” in the West End, which required copious dancing. But the actor admitted that one of his biggest regrets is that “after I finished ‘Billy Elliot,’ I quit dancing.”

Taking on the role of Astaire has given him an opportunity to step into a pair of dance shoes again and Holland revealed the project had even seen him return to the central London dance studio in which he’d first rehearsed for “Billy Elliott.”

Said Holland: “I’m so excited for the challenge.”
