I don't think the success of Brokeback Mountain will be repeated...
I disagree. I think it's going to be repeated again and again. Get name brand actors, known director, a niche script and a small budget -- throw them together and see what happens. A small money gamble by Hollywood standards.
No big name would ever do this, unless Richard Simmons or Andy Dick is a "name brand." Ha. How about Jack Nicholson and Sean Connery do a geriatric version? Yuck!! Never going to happen.
