This still from "To Be Or Not To Be" is the closest I could get to picturing Carole Lombard -- who never made a sci-fi film -- as Carrie Fisher's Princess Leia of "Star Wars" fame:
Why do I bring this up? Because my Facebook friend Dan Day Jr. just did an entry for his "The Hitless Wonder Movie Blog" ("Hitless Wonders" is a reference to Dan's beloved Chicago White Sox) on the intriguing "what-if" topic, "If 'Star Wars' had been made in the 1930s..." Not that weird a topic, as George Lucas meant to evoke the adventure serials of that era when he made the film. (http://dandayjr35.blogspot.com/2017/05/if-star-wars-had-been-made-in-1930s.html?spref=fb)
Anyhow, here's the cast he came up with. Nope, Carole's not included, but my second favorite classic-era actress is, along with many other '30s notables.
Luke Skywalker: James Stewart (presumably the young, pre-1939 "Jimmy")
Princess Leia: Myrna Loy (with William Powell in "I Love You Again"; this white dress of hers looks rather princessy)
Han Solo: Clark Gable (the Rhett Butler of sci-fi?)
Obi-Wan Kenobi: Lionel Barrymore (yes, the man who'd later be dastardly Mr. Potter here would be "our only hope")
Grand Moff Tarkin: Basil Rathbone (pre-Sherlock Holmes)
Darth Vader: Boris Karloff (perfect casting!)
C-3PO: Franklin Pangborn (a prissy robot? Why not?)
R2-D2: Billy Barty (certainly the right scale for the role)
Chewbacca: Noble Johnson (well, he had the facial hair to play a Wookie)
An fascinating cast -- and since Stewart, Loy, Gable and Barrymore were under contract to MGM in the late '30s, a film like this could've been made...although I can't imagine Irving Thalberg (had he lived) or Louis B. Mayer wanting to make a sci-fi adventure.
Day may come up with "Star Wars" what-ifs for other decades. We eagerly await his selections.
