Jerry Seinfeld and Jim Gaffigan chat with “Extra’s” Mona Kosar Abdi about “Unfrosted,” which tells the origin story of the Pop-Tart, an American breakfast favorite. Jerry, who stars in and directs the movie, shared how the project came to be during COVID lockdown. He also spoke about recently helping his buddy Larry David wrap up 12 seasons of “Curb Your Enthusiasm” by basically remaking the “Seinfeld” ending! “Unfrosted” is on Netflix May 3.
