Harvey Keitel is a 'Little Focker'

Harvey Keitel has joined the cast of 'Little Fockers'.

The 'Reservoir Dogs' actor will join 'Sin City' star Jessica Alba and 'Jurassic Park' actress Laura Dern in Ben Stiller's comedy sequel, which follows hits 'Meet The Parents' and 'Meet The Fockers'.

While it's unsure what part Keitel will play, the film charts the progress of married couple Greg and Pamela Focker as they juggle their warring parents and new children.

The film's regular stars Ben Stiller (Greg Focker), Teri Polo (Pamela), Blythe Danner and Owen Wilson are all returning to their roles for the third film.

However one of the film's other returning stars, Robert De Niro - who plays Ben Stiller's father-in-law - likes shooting the films so much he doesn't mind whether it does well at the box office.

He recently said: "I don't know if I can say it's the best one, that's for the audience to decide - but we're having fun."
