Have any actors ever played the role of father, and son of the father in the same movie?

I'm not quite sure what you mean as your question can be taken two ways, if you mean real life father and son or mother and daughter playing those roles then here are some examples - Wall Street(Martin and Charlie Sheen), It Runs in the Family (Kirk, Michael and Cameron Douglas playing Father, son and Grandson), The Great Buck Howard (Tom and Colin Hanks), John and Jason Ritter (The Dreamer of Oz: The L. Frank Baum Story), "The Pursuit of Happyness. and After Earth (Will and Jaden Smith).

I cant find many actors who have played both father and son in the same movie, mainly just Eddie Murphey films i.e the Kranks, this link may help though - http://en.wikipedia.org/wiki/Actors_who_have_playe...

Mother and daughter playing Mother and daughter -

Meryl Streep and Mamie Gummer in Evening

Vanessa Redgrave and Natasha Richardson in Evening

Blythe Danner and Gwyneth Paltrow in Sylvia

Susan Sarandon and Eva Amurri Martino in The Banger Sisters

Diane Ladd and Laura Dern in Wild at Heart, Citizen Ruth, and the series Enlightened

Demi Moore and Rumer Willis in Striptease

Leslie Mann and Iris and Maude Apatow in This is 40 and Knocked up

Laurie Simmons and Lena Dunham in Tiny Furniture

Will Smith and his son just did that movie After Earth

Eddie Murphy's the best example for this.

eddie murphy did in "the nutty professor" movies and mike meyers did it in "so i married an axe murderer" there are probably more
