Re: Another Chan-actor-filled movie: "Across the Pacific" (1942)
"Across the Pacific," AKA "The Maltese Falcon (gang) Goes to War," is another great film to spot Charlie Chan actors in non-Chan roles. I love the scene where Victor Sen Yung tries to be Bogart's pal. (Yung to Bogart: "We should hang out.") Bogie brushing him off. (Bogart to Yung: "In your dreams.") I'm paraphrasing a tad. It's great fun between Bogart and Yung.
If you like this film, check out "The Man With Bogart's Face" (1980). In every scene that Mr. Yung appears in, he has a falcon on his shoulder. A reference to above mentioned film.
