Gregory Peck leads a ridiculously talented cast in the 1969 film Mackenna’s Gold, directed by J. Lee Thompson. The cast also includes Omar Sharif, Telly Savalas, Camilla Sparv, Keenan Wynn, Julie Newmar, Edward G. Robinson, Raymond Massey, Lee J. Cobb, Burgess Meredith, and Eli Wallach.
Clint Eastwood was one of the first actors considered for Gregory Peck’s role but he had a commitment to make another western, Hang ’em High.
Apparently Gregory Peck enjoyed making the film with Edward G. Robinson and enjoyed his company on the set. The two talked about religion, politics, acting, and the fine arts.
You can find Mackenna’s Gold on dvd (Amazon link) or watch the movie on Prime Video.
