Captain Thunder (1930)

A notorious Mexican bandit goes all soft and mushy when he falls for a beautiful senorita. Warner Bros.' Captain Thunder contains some of the darndest Mexican accents you've ever heard in your life. The star is Hungarian-born Victor Varconi, portraying a legendary south of the border outlaw who tries to force Canadian senorita Fay Wray to marry a rival rustler whom she despises. She pleads with the bandito so pathetically that he is moved to grant her a single wish. Without hesitation she chooses her poor but true love. The bandit king, being a somewhat honorable fellow grants the wish and without a twitch, guns down the wicked cattle thief. Fortunately the film was played for comedy, a wise decision since it probably would have garnered laughs as a straight drama anyway.
