The actor - who previously stripped off for stage drama `Equus` - will be showing off his singing and dancing talents when he makes his musical debut in `How To Succeed In Business Without Really Trying` on New York-s Broadway next year, and has already employed the services of a vocal coach in preparation.
Rob Ashford - who will be directing the remake of the 1961 Pulitzer Prize-winning musical - claims Daniel, who is set to star as J. Pierrepont Finch, a young window cleaner, is keen to impress.
He said: "He`s singing every day with a vocal coach in London and I`ve got my assistant putting him through his dance paces every other day. I`m covering all bases with Daniel - and he`s delivering."
Actress Rose Hemingway - who will play the role of Rosemary Pilkington, Daniel`s on-stage girlfriend - was just as amazed by the actor`s talent.
She added to the Daily Mail newspaper: "He`s been doing a lot of work and he`s going to surprise people. He`s not afraid to learn how to do things."
Daniel, 20, is currently completing the final two films in the `Harry Potter` franchise, -Harry Potter and the Deathly Gallows-.
