Harry Potter actor Jason Isaacs has admitted that he hasn't even read the script for the fifth film.

"They started without me. Like most things in my life. I haven’t even read the script yet," Isaacs told Empire. "To be honest, I don’t know what happens in it. I know that I’m meant to end up in prison - that’s no great secret.

Asked about whether he will make an appearance in the movie, he replied, "I hope so, I can’t bear the idea that somebody else would get to wear my Paris Hilton wig, but you never know."

He added, "The wig is on time-share with Paris Hilton and she comes round. It takes a lot longer to prise it off me at the end of the day because I fancy myself as the lead singer of Sweet. Nah, it’s not very long, they’re all terribly slick with it. I miss it. I like the wig."

Isaacs plays Lucius Malfoy in the movies.
