No, because as I said, a star's name being attached to a movie doesn't guarantee success anymore like it used to. Look at any other "A-Listers" at the moment: 2 of George Clooney's last 3 movies as an actor didn't even cross $100m worldwide. Descendants had major Oscar buzz on its side. Brad Pitt's last movie failed to even make back its very modest budget domestically. Johnny Depp's last 2 movies as a lead, one of which was an expensive "blockbuster," bombed. RDJ has success in his popular blockbusters, but right on the heels of his success with Iron Man and Tropic Thunder, The Soloist did nothing. "It Girl" of the moment Jennifer Lawrence headlined a massive hit in the Hunger Games, but The Silver Linings Playbook, for which she is getting all the buzz, remains lukewarm at the box office despite being hailed as a "crowd pleaser."
No actor guarantees box office success these days. Not even Tom Cruise. But the success that his own franchise vehicle has seen since his psychotic antics proves that those antics are not the problem with audiences. It's the movies themselves and the studios' inability to sell them that are the problems.
