Sundance 2013 Adds Four Films Including Quentin Dupieux's Work In Progress With Marilyn Manson And 'El Mariachi'

We're just over a month away from the 2013 Sundance Film Festival and I can almost feel the slushy snow seeping through my boots already. The line-up is already incredibly impressive, as it includes world premieres of Ashton Kutcher in jOBS, the new Shane Carruth film Upstream Color, Richard Linklater's Before Midnight; and the horror sequel S-VHS just for starters. (Click on those links to read our coverage of each film so far.)

Plus, the real gems of the festival are rarely the movies you've heard of beforehand. Who heard of Beasts of the Southern Wild before last year's festival?

Sundance has just add four new movies to the already impressive line-up and each is weirder than the next. One is about the birth of a musical genre featuring the biggest names in music, the next features Michael Cera traveling to Chile, the third is an in-progress film by Rubber and Wrong director Quentin Dupieux starring Marilyn Manson and Eric Wareheim and the last is one of the most influential films to ever come out of the festival: a return screening of Robert Rodriquez's El Mariachi. Read about all the films below.
