Sans Leo, Marty tops out at 82 million.
Being generous, if the production budget is on the low end of 100 million and the marketing is the average 50 million, you're getting into domestic box office numbers that Scorsese just doesn't see and I doubt this is a film that people want to rely completely on foreign markets for the profit.
Beyond that, Hollywood's probably never investing 150 million in the production of an R-rated film starring three 70-year-olds, no matter what the names. Unless it's Cocoon meets Avatar and even then it would be a struggle.
