This is definitely not my challenge, I half-recognize pretty much all the characters but the only two I know are:
18. Mark “Rent-boy” Renton (Trainspotting) < Favourite movie ever!
21. Tony Wendice (Dial M for Murder)
I guess I'm not gonna win this one, I really wanted to make a comeback this challenge and avenge Adam but I guess that'll have to wait until next round.
