For Radcliffe has been at the centre of a bitter feud between Broadway producers for his latest theatre project and his former Harry Potter bosses.
They were allegedly upset when they learned that the British actor had signed on for How to Succeed in Business Without Really Trying in New York.
Radcliffe's run in the play takes place between February 26 and November 6 with Warner Bros. premiering Harry Potter and the Deathly Hallows: Part 2 in London on July 7.
During 'tense negotiations' the show's producers refused to release Radcliffe to promote the movie - forcing Warner Bros. to buy out the whole theatre for that nights he will miss.
'This is the final film, so it's a big deal,' an insider told the New York Post. 'The studio absolutely could not do it without their big star.
'But the theatre producers dug their heels in and would not release Daniel unless Warner bought out the entire theatre for the nights they need him.
'Studio bosses are furious, but they have no choice but to pay up for five nights costing over $500,000.'
A representative for Radcliffe told the Post that any difficulties have now been sorted out.
'Everything is fine, Dan is promoting the film and is happy to do so,' the rep said.
