It's on YouTube!
I just found this and watched it this evening! I finally got to see the great Ronald Colman in one of his many silents!
Other actors you'll recognize are Neil Hamilton (later in life to be "Commissioner Gordon" in the Adam West/Batman TV series), William Powell and Victor McClaglen. Wallace Beery's brother, Noah Beery Sr., plays the same cruel and ruthless sergeant who would later be portrayed by Brian Donlevy in 1939 and Telly Savalas in 1966.
Here is the link to "Beau Geste" (1926):

When you get there, you will soon note that there is a strip of "tape" on the screen; evidently, the person who posted this film must have pirated it from a television broadcast and realized the necessity of blocking out the broadcaster identification logo!
