They still show out for other movies.
I'm not on some anti-Will Smith shyt, but the writing has been on the wall for that late 90's A-List Hollywood gang.
Their time has been and gone, now it's time to do interesting movies instead of swinging for the fences. They shouldn't "give up", but the days of putting WIll Smith in a $50 million dollar movie that would be a $15 mllion dollar movie for someone else and expecting to almost recoup out of the gate is done for.
Nowadays it's not about the star as much as its about the hook. We can see stars anytime now, half of them never shut up on Twitter or Facebook. So the key is seeing them in something that looks interesting; you can't just put Will or Tom Cruise or Tom Hanks in any flick now and assume it's going to be a hit; there has to be a hook to it that makes it look interesting to the public
