We Name the Cast...You Name the Movie!

This month, we're hosting a different game at the Café! For each movie below, we have listed three performers that appeared in it (not necessarily as a star). Your task is to name the movie! As always, please answer no more than questions per day so more people can play and have fun. Try not to research your answers as it'd be pretty easy to google the cast and get a film's title. We avoided really obscure movies and lesser-known actors and actresses. 

1. Walter Matthau, Victoria Principal, Lloyd Nolan.

2. Strother Martin, Robert Duvall, John Fiedler.

3. Strother Martin, Heather Menzies Urich, Dirk Benedict (spelling counts on this one!).
