This whole thing, much like every version of GREASE since the film (it seems), is a crazy mess. I'll definitely be watching though, hopefully I don't fall asleep like I did with PETER PAN."
Pretty much how I feel. And I don't actually think Tveit is too old for the role, either; I honestly always thought part of the humor was that the T-Birds look way too old to be in high school, as if they've been too lazy to pass classes.

Starts out as FBI by-the-book perfection, currently has a possible painkiller addiction, a murder coverup in his recent past, and a classic beard (or scruff) of angst.
