The most realistic and complex time travel movie ever made. It strips away the glamour to show the gritty, confusing, and dangerous reality of causal loops.
In a suburban garage, two engineers accidentally discover a side-effect of their error-checking device: it's a time machine. There are no special effects here, only the terrifying realism of what would actually happen if ordinary men discovered god-like power. As they exploit the timeline for stock market gains, their friendship fractures under the weight of paranoia, double-crosses, and the physical toll of rewriting reality.

Explore the time-bending mechanics, paradoxes, and storytelling genius behind Primer.
Two engineers accidentally invent a time machine and become entangled in overlapping timelines. It's the most technically complex time travel film ever made.
Its ultra-low budget indie approach deliberately omits exposition, requiring viewers to piece together multiple timeline iterations and paradoxes.
Shane Carruth wrote, directed, produced, starred in, and composed the music—all on a $7,000 budget.
Relatively—Carruth grounded it in plausible physics concepts, avoiding typical Hollywood time travel tropes for rigorous scientific speculation.
Most viewers need 3-5 viewings with timeline diagrams to fully grasp the layered paradoxes and character duplicates.
