Megan Fox and Colson Baker (aka Machine Gun Kelly) Thrill in 'Midnight in the Switchgrass' Trailer (Exclusive)

Bruce Willis and Emile Hirsch co-star in director Randall Emmett's thriller.

If you only know of Megan Fox and Machine Gun Kelly's romantic saga, you may be surprised to learn Fox and Colson Baker (MGK's real name) first met professionally on the set of Midnight in the Switchgrass. Because judging by the movie's first trailer, which ET is exclusively debuting, the experience was intense.

In director Randall Emmett's thriller, FBI agents Lombardo (Fox) and Helter (Bruce Willis) team up with a Florida state cop (Emile Hirsch) to catch a serial killer (Lukas Haas) who abducts young girls from truck stops. "We're supposed to be protecting these girls," Fox's Lombardo argues in the footage.

And so, she goes undercover, first in a hotel room sequence opposite Baker's character -- in which she promptly beats him to a pulp -- and then a sting operation which goes horribly wrong, leaving Lombardo's life hanging in the balance amid a twisted game of cat and mouse. "The minute I got made bait, it became my operation!" she argues with Willis' Helter. Check out the brutal, bloody red-band trailer above.

Emmett, who may moonlight on Vanderpump Rules but whose primary job is as a producer (with more than 115 credits to his name), marks his feature directorial debut with Midnight in the Switchgrass. Fox was his first choice to play the lead, telling ET's Lauren Zima, "She's been doing this at a very high level for a long time. I went to Megan first, and I was shocked that she said yes."

Fox, meanwhile, calls Bruce Willis "a legend," "an icon" and "the nicest human person I've ever met," while she says of her co-star-turned-significant other, "I don't know if people understand what a good actor he is. He is so charismatic and he's so naturally gifted and he's so intense."

"He's really unbelievable as an actor," Emmett adds. "He's really talented."

"Which is annoying because he's also a brilliant, creative genius as a musician. So then, for him to show up on set and just be so much better than you at what you do for a living is very annoying," Fox deadpans. "But he's really gifted. He's an amazing actor. He's going to win awards one day."

If there is one word to describe Midnight in the Switchgrass' production, it's unexpected. Fox initially signed on to shoot for eight days but after a number of production shutdowns and six months of delays due to the pandemic, it beat out Transformers: Revenge of the Fallen by one month as the longest movie she's ever worked on.

"Everything that could happen in the process of making this movie has happened," Fox says. "We had hurricanes. We had sandstorms. We have wildfires. We had all the things. These are the ones that you do remember forever and you will look back, Randall Emmett, and laugh about all of these things. One day when you're not stressed anymore, you're going to look back and laugh and be like, 'F**k. It was actually kind of fun.'"

"We have all become very close. And I really don't believe that any of us would have the friendships and relationships that we had had COVID not hit, had we not shut down," Emmett says for his part. "We spent six months together on a movie that's supposed to be four weeks long total. And for me, that became really special."
