The Rock just revealed his latest action movie, co-starring Siri

Dwayne "The Rock" Johnson says a lot of things on social media, including the occasional dad joke, but unless he's pranking us this time, we're about to see him star in a film with none other than Apple's digital assistant, Siri.

"I partnered with #Apple to make the biggest, coolest, craziest, dopest, most over the top, funnest (is that even a word?) movie ever," wrote Johnson on his official Facebook page. "And I have the greatest co-star of all time - #SIRI."

It's unclear what the nature of the film is, but since it's unlikely that a full-length feature from one of Hollywood's biggest stars would just get dropped on us with one day's notice, it's more likely a promotion of some sort to show off some of Siri's features. And since Apple has also been touting the iPhone as a filmmaking tool, it's likely the "film" will be shot on an iPhone.

Whatever the actual film turns out to be, the poster Johnson revealed with the announcement is pretty well done and promises robot monsters, space travel, and car chases. But that's probably just poster hype, right?

"I make movies for the world to enjoy and we also made this one to motivate you to get out there and get the job done," wrote Johnson. "I want you to watch it, have fun with it and then go LIVE IT."

The film, titled The Rock x Siri will debut tomorrow on Apple's YouTube page.
