Will Smith is reportedly causing huge disruptions to his wife's TV show.

The 'Men In Black' actor has been spending a lot of time on the set of medical drama 'HawthoRNe' - in which his spouse Jada Pinkett Smith plays a nurse - because his lack of filming commitments have given him more time to devote to his role as producer on the show.

But he has allegedly been infuriating cast and crew by submitting "pages of notes and rewrite requests" every week.

A source told the New York Daily News newspaper: "He is not currently shooting a movie, so he's been a constant on the set in recent weeks.

"He's been inserting his input and requesting so many changes to the script that it pushed back the production schedule tremendously and caused everything to spiral out of control.

"Everyone is praying for him to book a new movie so that he will go away."

Will is currently making a decision on whether his next movie will be 'Men in Black 3' or 'City that Sailed' but has no definite filming commitments lined up.

Jada recently revealed her husband wants to be the US President.

She said: "Will is thinking about going into politics. He once said he could imagine becoming US president. He wasn't joking, he was quite serious about it."
