An adaptation of Michael Kun's 2003 novel The Locklear Letters updated for the social media era, the film stars Tony Hale as Sid Straw, a man who becomes co-chair of the University of Pennsylvania planning committee for his college reunion, only to become obsessed with proving that he was friends with actress Elizabeth Banks in their student days.
Sid is a software company manager who is asked to help plan a reunion for West Coast graduates of the University of Pennsylvania. One of the graduates is Elizabeth Banks. She knew him in college and Sid sends her numerous messages, not realizing they are public. Elizabeth's agent Frankie finds out he is sending the messages and gets concerned that Sid is a stalker. Sid asks for an autographed photo for his brother Tom's birthday but it is messed up and he has to ask for a replacement. Frankie finally has a restraining order issued which Sid vows to fight. However, Sid goes viral and loses his job. Sid finds a cheap lawyer James to fight the restraining order but has to wait for the lawyer to pass the bar. When Sid goes before a judge he is unable to produce sufficient evidence to get the restraining order dropped. As the judge is about to rule, Sid remembers the story of how Elizabeth inspired the volleyball team to play harder against a very good team. The judge rules in Sid's favor. Sid goes to the reunion and gets another job. Tom's wife gives birth and while Sid is visiting he gets a phone call. Though he doesn't answer, Elizabeth is heard by the movie audience leaving a message telling Sid how she remembers him fondly and has been filming a movie out of the country. As she used to do, she says goodbye by saying, "Eat Wheaties."

The film was positively reviewed by film critics, with a Rotten Tomatoes score of 68% and Lou Harry of the Midwest Film Journal writing "Eat Wheaties! is one of my favorite films this year. Honestly. It's got the cringe-laughs of a good episode of Curb Your Enthusiasm but with a sweet, gentle heart beating inside it." Gabriel Sigler of Bad Feeling wrote that "Eat Wheaties! is one of the most enjoyable films of the year." The critical consensus on Rotten Tomatoes reads, "It frequently fumbles its attempts to balance cringe comedy and sincere drama, but Tony Hale's charm helps keep Eat Wheaties! from getting soggy." Richard Roeper's three star (out of four) review in the Chicago Sun Times noted "in the hands of writer-director Scott Abramovitch and with the considerable contributions of an outstanding cast that also includes Kylie Bunbury ("Big Sky") and Paul Walter Hauser ("Richard Jewell"), "Eat Wheaties" is a dryly funny, even sweet and surprisingly touching story".
