Same Spiel Different Movie. This is when an actor or actress plays the exact same type of character in two (or more) different movies.
Tom: Hey Ash, Michael Cera ALWAYS plays the exact same character. He's always this timid little guy who gets pushed around. I mean, Nick and Norah's Infinite Playlist, Superbad, Year One, Juno- he only plays one type of character.
Ash: Classic case of SSDM.
