No longer playing second banana to James Cagney, in "Sierra" Bogart was given a juicy breakout role as a killer with a compassionate side. It's clear "Mad Dog" Earle was at least partly modeled on criminal folk hero John Dillinger. Yet, even though Roy seems quite human and sympathetic at times, he’s still one scary hombre when threatened. Young Lupino (who’d go on to direct films) stands out as Earle's loyal protector who can't win his love. Co-written by a young John Huston, "Sierra" is a solid, flavorful entry for "Bogie-as-bad-guy" fans, boasting a slam-bang finish.
