Will Arnett is not funny at all. Not even accidentally. He wants to be, he’s a fan of funny… but he’s not. Why the fuck is he in so damn many movies lately? Maybe the lack of Hollywood creativity just started with casting directors?
As for Cera, Anyone who ends up in one of these media popularized movies will be able to benefit from being stuff into roles for no reason for at least a while. In this case he was in two; Superbad and Juno. We saw the Jonah Hill stuffed into everything for no reason the moment Superbad hit the box office and it still doesn’t see to be totally over. At least that guy can be funny sometimes. With Michael Cera there is no talent to speak of, so maybe it will wear off faster. We can only hope. Kat Dennings is the one I don’t want to see in movies anymore, I can’t stand to look at her. At all.
