Tom Hanks forced his way into his son's new movie.

The Oscar winner was so impressed with the script for 'The Great Buck Howard' he decided he wanted to play his son Colin's onscreen dad whether he liked it or not.

Tom, 52, said: "I selfishly attached myself as the dad. I didn't even ask Colin, I just said, 'Hey listen, I'd like to play the dad.' He kind of rolled his eyes and said, 'Well yeah, I can see why.' And that was that."

The movie - which also stars British actress Emily Blunt and premiered in New York this week - tells the story of a young man who accepts a job as the assistant to a jaded illusionist, played by John Malkovich.

Emily plays a pushy publicist in the film and admits she learnt a lot about how to portray her character from her own experiences in the movie industry.

She said: "I see a lot of PR people at photo shoots and the red-carpet events where they are flapping around their clients. Mine, Rupert, certainly is never like that. But I've been witness to that sort of thing. I did steal from a few situations I've been in or been witness to."
