One of the greatest breakouts of the past five years was David Lowery’s Texan crime-romance Ain’t Them Bodies Saints, which starred Casey Affleck and Rooney Mara. It got Lowery on Disney’s radar to helm this summer’s Pete’s Dragon (which is fantastic), but the trio hasn’t worked together since that first 2013 film. Or so we thought — it appears that Affleck, Mara, and Lowery secretly got together over the summer to make a mysterious new film.

Per The Film Stage, Lowery and Affleck will be reteaming for Robert Redford’s final performance in The Old Man and the Gun, but Lowery had hinted that he wanted to make a more independent project last summer, while talking to Filmmaker Magazine about Pete’s Dragon.

I wanted to make something small and tiny and handmade. I don’t know what it is yet, I’m kind of figuring it out. I had the urge to just go make something spontaneously, like I used to do. I would have an idea and go make it, either a short film or an experimental idea. Over the past few years I stopped doing that as much, and I really wanted to get back in the habit of getting some friends together and shooting something. It’s a good habit to be in as a filmmaker. I basically wrapped [postproduction] on June 10th and the next day flew to Dallas and started working on whatever this thing is that we’re making.

Check out some Instagrams of production below, as well as an interview in which Casey Affleck confirms the new project.
