After the release of “The Matrix” back in 1999, there was renewed interest in the time-tested theory that the world around us is a simulation. And now, even today, perhaps more than ever before, that theory is still being discussed. Enter the new documentary, “A Glitch in the Matrix.”

As seen in the trailer for the new doc, “A Glitch in the Matrix” tackles the notion that reality is just a simulation. With inspiration from a Philip K. Dick speech, the film goes through the painstaking process of trying to figure out if we are all living in The Matrix. And yes, there is plenty of footage from cultural touchstones, such as the Wachowskis’ film.

“A Glitch in the Matrix” is directed by Rodney Ascher. The filmmaker is probably best known for his work on the docs, “Room 237” and “The Nightmare.” His latest film premiered at this year’s Sundance Film Festival.

In our review of the film, we said, “Rodney Ascher’s computer-haunted documentary ‘A Glitch in the Matrix’ is not the most insightful recent examination of boredom-born foggy Internet delusions. That honor likely goes to Arthur Jones’ antic ‘Feels Good Man.’ Still, Ascher’s appropriately discombobulating stew of queasiness, comedy, and terror seems well-cued to the subject matter, even while missing a certain editorial sharpness that might have brought some of its notions into greater clarity.”

“A Glitch in the Matrix” is now available in theaters and on VOD. You can watch the trailer below.

Here’s the synopsis:

What if we are living in a simulation, and the world as we know it is not real? To tackle this mind-bending idea, acclaimed filmmaker Rodney Ascher (ROOM 237, THE NIGHTMARE) uses a noted speech from Philip K. Dick to dive down the rabbit hole of science, philosophy, and conspiracy theory. Leaving no stone unturned in exploring the unprovable, the film uses contemporary cultural touchstones like THE MATRIX, interviews with real people shrouded in digital avatars, and a wide array of voices, expert and amateur alike. If simulation theory is not science fiction but fact, and life is a video game being played by some unknowable entity, then who are we, really? A GLITCH IN THE MATRIX attempts to find out.
