The star took to the BET Awards stage on Sunday to introduce a clip from his upcoming action comedy, and he took the opportunity to slam another film he recently worked on.
"I can't wait to tell you about that joint Baby Driver! It's crazy, it's cool, and it ain't a typical film. It brings a thrill ride, so everybody can experience it," Foxx said, smiling. "And it's good too! It ain't like that last joint I had."
Foxx laughed as fans in the audience were somewhat surprised by his off-the-prompter candor, and the 49-year-old actor powered on. "I know, it's tough. It's tough when you still gotta promote it."

"You know it's bad when they don't ask you nothing about the movie like, 'Man that jacket you was wearing is tight,'" he continued, referring to awkward press junkets. "Yeah, I know it sucked."

Quickly, Foxx switched gears and brought thing back around to Baby Driver, telling fans, "Have your ass at the movie theater," when the high-octane crime dramedy comes out June 28.
While Foxx didn't specify which movie it was that he thought "sucked," the actor's last film was Sleepless -- a critically panned crime thriller that came out in January. Prior to that, Foxx hadn't appeared in any movies since 2014's remake of Annie.
Foxx spoke with ET's Kevin Frazier on the silver carpet ahead of the show, and the star had nothing but praise for his upcoming film.
"Baby Driver is amazing man. Listen, I don't know how much you buy into critics, but it's 100 percent on Rotten Tomatoes," Foxx said. "Everywhere we premiere it has been gangbusters."
By comparison, Sleepless currently has a 21 percent, which is a far cry from Baby Driver's so-far perfect score.
"It's good to have a good one. You know, it's hard when you're out there promoting and you know it stinks," he added. "I've had a couple of them where I just know it stinks."
Foxx recently spoke with ET about Baby Driver, where he also revealed that he once let Ed Sheeran crash on his couch when the "Shape of You" singer was still an unknown artist trying to make a name for himself.
