Hollywood is full of mysteries. Does Tom Cruise really wear platforms during kissing scenes? Why do British people do the best Southern accents? Is Halle Berry aging backwards? All valid questions, but one of the biggest is: Why do some movie stars keep getting work, despite evidence that they should probably take a seat (or rethink their career choices)? Most of these actors fall into two categories: either their talents are being misused (Cameron Diaz), or they're completely overrated (like Kristen Stewart. Sorry). In both cases, their handicaps haven't stopped them from being some of the most prolific celebs in the biz. From Adam Sandler to Jessica Biel, check out some of the most constantly-working-for-no-reason actors in Hollywood.

Watch as Diaz shows off her knowledge on the subject matter (sex) of her most recent film (Sex Tape), below.
