Alan Alda and wife Arlene at the Movie premiere of "Find Me Guilty" at the Sony Lincoln Square. New York City, USA - 14.03.06

The former M.A.S.H. star, 70, and Arlene, celebrate their 50th wedding anniversary next March (07) - a rarity in Hollywood, where couples regularly split after only a few years of marriage.

Alda says, "Spite and malice - the card game of course! We play it every day.

"By the end of the game, we're cursing and laughing."
