A massive cast makes up Netflix’s upcoming historical comedy Unfrosted, Jerry Seinfeld’s directorial debut about warring cereal rivals in the 1960s.

The trailer above teases Kellogg’s and Post going up against each other to try to create the ultimate breakfast pastry, and pretty much everyone we see on screen is a big name. Alongside Seinfeld (who also co-wrote the movie), 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 yıldız.

How to watch: Unfrosted is streaming on Netflix from May 3.
