Primer (2004) dir. Shane Carruth

Four friends and entrepreneurs accidentally discover a dangerous means of time-travel. Perhaps the most “realistic” film on the subject of time travel, shot within five weeks on the minuscule budget of $7000. An intelligent and complicated movie with a unique concept and multi-layered plot. 

Despite it’s low budget, Primer won the Grand Jury prize at Sundance Film Festival and was a box office hit, and is now considered a cult-classic.

Primer Cast: Shane Carruth, David Sullivan, Casey Gooden, Anand Upadhyaya
