Have you ever watched a movie thinking that one of the stars was someone else? Well, it probably happens a lot with these 10 stars -- in fact, they probably get recognized on the street and asked about movies they weren't even in.

There are even stars who don't look that much alike that are easily confused.

Consider Bill Pullman. The star of such hit films as Dumb And Dumber and Twister -- er, wait a minute, that was Jeff Daniels in Dumb and Dumber and Bill Paxton in Twister (okay, so this isn't a pair of stars, it's three).

Bill Pullman became a recognizable face thanks to Mel Brooks' classic Spaceballs. That was in 1987. Around the same time, Bill Paxton was being recognized for his role as space marine Hudson, aka the "game over" guy, in Aliens. Since then virtually everyone has confused the two.

As for Jeff Daniels, who closely resembles Paxton, he became a household name in the 80s also, adding to the confusion.
