I loved Brando as Jor El. The Wild One is extraordinarily dated, but worth seeing.
Greatest actor ever, but... coulda hadda better career. His highs were higher than anyone's (Streetcar, On the Waterfront, Godfather, Last Tango, Apocalypse, Julius Caesar), but the lows were pretty bad.
Edit:
OH! Orson Welles in Transformers. Yikes. Actually, it has a 7.1 rating on IMDB.
As I recall "Stromboli" was panned pretty roughly too.
But let's face it - Bergman at her worst was better than many at their best. And to her credit, it was the movies that were panned, not her performance in them.
She'll always be Elsa or Joan of Arc to me.
My favorite Ingrid roles are Under Capricorn and The Inn of the Sixth Happiness. She's so gritty in them--I could almost smell her in Under Capricorn, but that's Hitchcock. Puts her right up there with Bette Davis, who IMHO is the best actor ever, even if I'm not a fan of hers. Ingrid's #2.
Already panned James Stewart, Olivia de Havilland, and several other favorites. Gene Hackman is too easy (Superman's already been mentioned.) But Cary Grant also stumps me.
This dreadful movie also had a distinguished English actor--someone who's been in a ton of bad movies, has only ever won a BAFTA TV Award, spent time as a POW in a Nazi prison camp, and also portrayed a prisoner in one of the greatest WWII movies. IMHO, he's among the most underrated star actors of all time.
Please, NO! They both did some horror at the end of their movie career, but those were actually very good movies. Let them retain their grace and dignity.
