The Tom Hardy thread in the main page made me remind that the he was attached to "Suicide Squad" as Rick Flagg, but had to leave the project because he would be shooting The Revenant.
We know how this turns out. The Revenant is a great movie, while Suicide Squad... and Hardy acting skills would be wasted on Captain Exposition.
Which other actors avoided terrible movies\roles choosing to do something better? And which actors took the wrong decision and refused great roles for movies that turned out badly?
