If Julie Christie is the only thing you "get" out of this movie, you're definitely not a film fan. You're writing off Omar Shariff, Alec Guinness, Rod Steiger (If you cast Steiger, you got Steiger, and he's obviously what they wanted.), Ralph Richardson, Rita Tushingham, Tom Courtenay, Geraldine Chaplin, Klaus Kinski (in a great bit role!), and the rest of the remarkable cast; phenomenal cinematography; a brilliant script by Robert Bolt that has to boil down an epic novel into a workable form; one of the most beautiful film scores ever written; and a genius director~David Lean.
I'm not saying anything beyond this: It's not a product of its time, so how could it be dated in any way? What of the Sixties do you see in it~protesting perhaps? I don't believe that there's any way anyone could guess when this film was made unless he or she knows exactly when certain actors and actresses were working. It stands on its own as recreating a distant time and place, mixing beauty with tragedy.
Trivia: Ingrid Pitt was an extra~interesting only if you're a Hammer film fan I suppose.
