Sister Mary Benedict in 'The Bells of St. Mary's' (1945)
Just two years after she lost the Oscar to Jennifer Jones, Ingrid Bergman found herself cloistered in "The Bells of St. Mary's"—"Doubt’s" sweet-natured cousin. Like "Doubt," "St. Mary's" features a priest (Bing Crosby) and a nun (Bergman) who get on each other's nerves in a Catholic school. Only this time around, the protagonists are ludicrously wonderful people who, at the end of the day, just want what's best for their young charges.
The movie made scads of money (it was the highest-grossing film of 1945) and was nominated for eight Oscars—including for Bergman's performance as a stickball-playing nun. It's still considered one of the best sequels ever (it was a follow-up to Crosby's "Going My Way"), and rumor has it that director Martin Scorsese —yes, he of "Raging Bull" and the cinematic gangland killing—chokes up every time he watches the end.
