I'm sorry to say that, but without a good base, no movie can help you to learn Spanish. Specialy awful for that purpose are the "real" Spanish movies (like Almodovar's) plenty of colloquialism and the upmost made with a touch of Sapanish "every day language" a slang hard to understand even for latinoamerican people. The doubled movies, like American-made series double to Spanish can be more usefull for you, since they're made in a neutral Spanish without local slangs and a plain accent.

In school my spanish teachers have made us watch student production films made FOR students. One that comes to mind is Destinos, made from UIC and is an online series. Im not exactly sure where you could get it exactly but you may be able to look it up somewhere. Its not a 'beginners' spanish movie but Pan's Laberinth(sp?) is a great movie all in spanish.
