Theater_Nerd, Ferrara and Rodriguez are definitely on the older end of things. I guess this is most important with the character of Daniela who's journey is very specifically tied to that of a 18/19 year old. I know Vanessa is supposed to be around the same age as Daniela, but I don't see a reason to stick to that for the film. In fact, I like the idea of an older Vanessa, especially if it means the incomparable Gina Rodriguez can play the role. I can't think of someone who would fit Daniela in terms of age and vocals and who is also a Latina (no Vanessa Hudgens, please--don't have an issue with her but she's not a Latina).
I'm actually really excited about this film. I think IN THE HEIGHTS is one of the great underrated musicals, and I can see it working beautifully as a film. In the hands of the right director, "96'000" and "Carnaval del Barrio" could be as spectacular as the "Tonight (Quintet)" in WEST SIDE STORY or "Cell Block Tango" in the CHICAGO film. Oh, and BrodyFosse, thank you for the links re Vergara's previous involvement.
