Even though it's not technically a Latino film festival, the Miami Film Festival always has one of the best selections of Latino films in the country. There are too many films to list, but here's some special programs to look at:
The Knight Competition has films from Uruguay, Mexico, Cuba, Argentina, and Spain competing for a $40,000 prize; salsa, bossa nova, calypso and more are explored in Reel Music; and the HBO Ibero American Competition includes 16 films.
Miami: March 9 - 18. Full lineup and details here.
