Harry Potter actor Jason Isaacs today revealed that his behind-the-scenes home videos on film sets capture stars behaving 'Incredibly badly'.

Isaacs, who plays warlock father Lucius Malfoy in Harry Potter and the Chamber of Secrets, said he has compiled the tapes whilst working on a series of Hollywood blockbusters.

Though most of the footage is private, excerpts shot whilst he played villain Captain Hook in 2003 version of 'Peter Pan' are to appear on a forthcoming DVD release of the film.

"Lots of people behave incredibly badly on the set and I just go *ahem* and point at my camera," said the British star.

On 'Armageddon' I've got (director) Michael Bay doing his Michael Bay shtick, climbing the walls and screaming.

'He says, "You're not filming this are you?" "Yes." "What are you going to do with it?" "I don't know , I guess sell it to network television".'

Isaacs, who also starred in Black Hawk Down, explained that he first took photographs of film productions, before creating his own films.

"I always video everything. What they put together on the DVD is a few minutes of fun. But I have the *Hearts of Darkness* version," he said, in reference to the famed documentary about the troubled production of Apocalypse Now.

"I've got everything and I always have enough to burn some bridges if I don't want to work again. I guess I like hiding behind the lens."

Though the cast worked to strict rules on the 2002 Harry Potter production Isaacs said he was still able to film, but ordered not to release the footage for public viewing.

He said: "That was the one place where you were not meant to have any cameras.

"That didn't stop me from shooting, but it did stop me from turning it over."
