Jason Behr
You probably remember actor Jason Behr from the 90s hit drama Roswell, where he played an alien in disguise who frequently tried to insinuate to the other characters of the show that he was from another planet. Afterward, he starred alongside Sarah Michelle Gellar in the well-recieved remake of The Grudge.
However, like so many forgotten celebrities, Behr deiced to take a step back from Hollywood in 2006, after marrying actress KaDee Strickland, in order to raise a family. It seemed to work out as the two are still together! Meanwhile, Behr has decided to return to Hollywood and is now hard at work at the current Roswell reboot!
