I just want to see MJW in a role other than "fat girl faces adversity and gets boy at end of movie/play" Well I accidentally caught her in a teeny tiny role on an episode of Felicity this weekend (literally one scene) and the only adversity she was facing was an R.A. in a dorm who suddenly had to bunk up with more roommates.

She was heavier than as well and her hair was straight.
But on the subject of her as Tracy. The first time I saw Hairspray I saw Shannon Durig in the role and then went out and bought the soundtrack and kind of didn't appreciate the squeaky sound. I kept listening to it however and then may or may not have had the opportunity to see her play the role (not live on stage) and I realized that with her it seemed to be a case of putting all of the elements together to play the role, not the greatest voice ever, probably not the greatest dancer or actress either, but everything rolled into one made her very charming and appealing in the role. I recently saw Carly Jibson in the role and she has that same kind of quality and her take on Tracy (especially vocally) is quite different but packaged together she's fantastic.
Now whoever was playing Amber on the other hand... eeek. Not so good.
