Jeez, where I do I start on this subject?
I wish Richard Attenborough hadn't directed the film version of A Chorus Line.
I wish someone other than Helena Bonham Carter played Mrs. Lovett in Sweeney Todd: The Demon Barber of Fleet Street
I wish Katharine Houghton hadn't played Joey Drayton in Guess Who's Coming to Dinner? I'm pretty sure she only got the role due to being Katharine Hepburn's niece and resembling her but the woman can't act and kept a great film from being a masterpiece.
Patty Duke never should have agreed to play Neeley O'Hara in Valley of the Dolls, for my money, the worst single performance by an actor in cinema history.
I wish will Ferrell hadn't played Darrin the Bewitched movie...Jim Carrey should have played that part.
Diana Ross shouldn't have played Dorothy in the film version of The Wiz, Michael Jackson shouldn't have played the Scarecrow and Sidney Lumet shouldn't have directed the film.
Marlon Brando shouldn't have played Sky Masterson in Guys and Dolls.
Though I understand the casting and why it happened the way it did, Audrey Hepburn had no business playing Eliza Dolittle in My Fair Lady
