LeBron James spent his off day working on his next movie.

The Cavaliers star posted a video on his Instagram story of himself in the studio recording lines for the animated feature “Smallfoot.”

He plays Gwangi, a giant purple Yeti who, based on the lines James reads in the clip, appears to be a bit of a conspiracy theorist.

“Uh oh, I smell a cover up,” James as Gwangi tells his fellow bigfoot, Migo, voiced by Channing Tatum in the film. “We’re are just part of a big machine!”

This is James’ second feature film, following 2015’s “Trainwreck.” He is also reportedly working on a sequel to “Space Jam.”

“Smallfoot” also stars James Corden, Zendaya, Gina Rodriguez, Common and Danny DeVito. Look for it in theaters on September 28. Watch LeBron do his thing below.
