Putting it plainly: Whenever you walk up to a movie theater and see the names Ashton Kutcher or Charlie Sheen on the marquee, there's a pretty sizable chance that you are about to witness cinematic diarrhea. Despite their enormous popularity, both men flop more often than an international soccer team.

See, even though Sheen became a household name in '80s classics like Wall Street and Platoon, he has also bombed his way into theaters with duds like Scary Movie 3 and the truly dreadful Three Musketeers. In fact, after his partnership with the Oliver Stone fizzled in the late ‘80s, Sheen was relegated to cheap sequels and hokey comedies. Remember Hot Shots! Part Deux? If you don’t, then you are one of the lucky ones.

It wasn’t until he replaced Michael J. Fox in Spin City, and then later took on the lead in Two And A Half Men, that Sheen regained some respectability in Hollywood.

Respectability isn’t a word often associated with Ashton Kutcher’s career, though. His filmography reads more like a list of bargain bin DVDs at the local Best Buy, rather than the resume of an accomplished Hollywood actor. We'll admit That ‘70s Show was funny in the beginning, but does that really make up for Dude, Where’s My Car?, The Butterfly Effect, or Guess Who? Never. If there's a Blockbuster Video in hell, we can only assume that it will be filled to the brim with Kutcher's flicks.

The edge goes to: Ashton Kutcher
