Actors that cant make a bad movie...

[Lanzalot]

Denzel, Crowe and Hanks are all good answers, but I'm a little surprised no one has mentioned Morgan Freeman. Check out his run from about 1988 onward. Mostly good stuff.

But the clear winner is...

Al Pacino, 1971-1975 and 1989-present*. Subtracting for the two years that he made Gigli and S1m0ne that's still 20 years. [img]/images/graemlins/grin.gif[/img]
