Jerry Seinfeld's Star-Studded Unfrosted Trailer Presents a Silly Pop-Tarts Origin Story

Jerry Seinfeld is helming a comedic take on the invention of Pop-Tarts.

The comedian makes his film directorial debut with Unfrosted, a comedy that also features a star-studded cast: Melissa McCarthy, Jim Gaffigan, Hugh Grant, Amy Schumer, Max Greenfield, Christian Slater, Bill Burr, Daniel Levy, James Marsden, Jack McBrayer, Thomas Lennon, Bobby Moynihan, Adrian Martinez, Sarah Cooper and Fred Armisen.

Unfrosted is set in Battle Creek, Michigan, back in 1963, when "Kellogg's and Post, sworn cereal rivals, race to create a pastry that will change the face of breakfast forever."

Seinfeld, 69, tells PEOPLE he's "been obsessed with Pop-Tarts my whole life," sparking an interest in bringing this story to the screen.

"My friend Spike Feresten, who was a writer on my show and is still a good friend of mine, thought we should make a movie out of the story, the real story, which we did," he explains.

"There are elements of truth, obviously quite a bit is also fabricated," continues Seinfeld. "I would say 99% is fabricated, which was the fun of it. But I love the idea of serious people working on cereal and with suits and ties and talking about Pop-Tarts and cereal and eating cereal. I've always loved cereal." 

The comedian adds that the whole cast brought the laughs, especially Grant.

"Everybody loves Hugh Grant, but he loved the part, the idea of this broken-down Shakespearean actor having to play Tony the Tiger to pay the bills," says Seinfeld. "I've been in love with him since Four Weddings [and a Funeral] and he was so much fun on the set. We would just tease each other and have so much fun."

Unfrosted is on Netflix May 3.
