That is an all-timer for me, but for some reason I'm okay with a remake.
Now Karate Kid? That shat pissed me off, even though the new one turned out to be half way decent.
If someone could pull off one of these young roles, the types that all of those same actors (Anthony Michael Hall, Molly Ringwald, etc) would play in all of those 80's teens/high school movies, I think it's that kid from Scott Pilgrim. He's pretty goofy and he's funny.
I call him a kid but I think he's like 25, but he looks young and he's really goofy which is exactly what you need to play the role of one of the Weird Science guys, or Hall's character in The Breakfast Club.
I just hope they don't screw it up.
