I think Sutton Foster would be a terrible Evita in nearly every way, but I think she COULD pass as a teenage girl. Just not the kind of teenage girl that Eva Duarte is supposed to be.
If Sutton Foster is stereotyped as the quirky, funny heroine, why was she cast as Eponine in Les Mis? Eponine is, technically, quirky and funny in the original novel, and she saves Marius' life, which I suppose makes her a heroine as well. Most actresses choose to play up her pitiful and tragic sides, but not all of them.
In my pants, she has burst like the music of angels, the light of the sun! --Marius Pantsmercy
