Joaquin Phoenix is no Oscars slouch, but he could have had the lead role in "Brokeback Mountain," which later went to Jake Gyllenhaal. It turns out Matt Damon could also have had the role played by Heath Ledger, but he turned it down. "I had just done 'The Talented Mr. Ripley' and 'All the Pretty Horses.' I said, 'I just did a gay movie and a cowboy movie. I can't do a gay cowboy movie now.'"
