Actor Kevin SpaceyJon Hamm and Jamie Foxx star in the summer's most anticipated action movie, and it's equal parts heart-pounding thrills and toe-tapping musical.

Car crashes, romance and a musical backdrop make "Baby Driver" a genre-bending adrenaline kick from writer/director Edgar Wright.

“We had a very good blueprint to work with from Edgar,” Jon Hamm told Hot Topics digital producer Jessica Sooknanan. “Not only his script and his shot-list essentially. He had the whole movie story boarded out.”

The film stars Ansel Elgort, who plays a skilled getaway driver in Atlanta serving kingpin Kevin Spacey and cronies Hamm and Jamie Foxx.

Wright wrote nearly every scene to the beat of a killer song.

“Everything really, even to the syncopation of what he hears when we do ADR, he really wanted it to bound the right way. It was magical in that way,” said Foxx.

It turns out, shooting guns on-beat is harder than it looks.

"It was really hard," said Eiza Gonzales, who plays Hamm's love interest, Darling. "When Jamie shot, then I knew someone else was going to shoot and then I was there, but you had to have the beat."

You’re not going to want to blink in the caffeinated heist thriller, or you might miss a musical cameo.

“There’s a brief appearance by Big Boi and Killer Mike, Flea from the Red Hot Chili Peppers, Sky Ferrerira, Paul Williams, Jon Spencer. To be honest, I would have done even more,” Wright said.

“Baby Driver” opens in the U.S. on June 28.
