Alexz Johnson as a 1976 Stevie
Carey Mulligan as a 1976 Christine
Robert Pattinson as a 1976 Mick
Nicholas Hoult as a 1976 Johnny Mac
Really stumped for Lindsey. I'd say Bradley Cooper but he's too old for 1976. He'd be perfect for a TITN sequel.
Maybe Shia Lebouf...
some people might argue they have similar personalities.
