in its original presentation (language)?

i actually enjoyed this movie. an interesting premise and a fair tale of placing hope in something that logically has no hope...

like most, i rented this without knowing anything about this movie. i returned it before looking up info on it... does the dvd show it in its original language? it looks like it was released in spain only, but the dialogue is in english, so did they dub the whole movie is spanish for the theater? seeems pretty odd.
