I was watching a youtube video of the 100 greatest movie threats and I saw the Robocop one. I thought, "no way, that's not him!". I IMDB the movie, and sure enough, its Red from that 70s show!!! Who else has iconic roles that clash with one another? Also breaking bad.
Probably Peter Cullen voicing Eeyore and Optimus Prime and Mark Hamill playing Luke Skywalker and voicing the Joker.
It cracks me up how many people show up in a Star Trek episode that I know from elsewhere... Kim Catrall Sabrina Le Beauf (Sandra Huxtable from the Cosby Show) Ashley Judd Kirsten Dunst Iggy Pop Kirstie Alley Jason Alexander from Seinfeld Sarah Silverman Brian Bonsal (the little kid off of Family Ties and Worf's kid) James Doohan was the butler on the Nanny and Data's rival on TNG Kelsey Grammer Stephen Hawking The guy that played Dr. Kelso on Scrubs The King of Jordan (yeah, the real King of Jordan... lol) Brenda Strong off of Desperate Housewives James Worthy (ex-Laker) The Rock There are probably others, but those are the ones I could find. And for LCAhmed, the guy you're talking about (Kurtwood Smith) has also appeared in Star Trek episodes and movies : Spoiler
Oh man, I almost forgot another Star Trek regular, Nana Visitor, who played Kira on DS9 appeared on Night Court as one of the most deranged/zany characters ever on that show. And of course, Brent Spiner, showed up a few times as a hick on Night Court as well.
i remember watching Inception in the theaters and this guy was in the movie and i could not for the life of me recall where i'd seen his face. i didn't know JGL was in it. it irked me so bad i couldn't really enjoy the movie. finally, when it was over i asked my g/f who the hell that was. she said the kid from 3rd Rock from the sun. *facepalm*
