Timothée Chalamet shows off his college football knowledge.

The actor appeared on ESPN’s “College GameDay” on Saturday to preview college football’s weekend slate and showcase his deep understanding of the game.

The “Dune” actor was announced as a guest selector for “College GameDay” this week. This involves selecting the winners of some of the top games that will be broadcast on Saturday.

“These teams are in second and second place in their last four meetings. The RedHawks defense looks good, but I’m looking at fourth-year Bobcats quarterback Parker Navarro…If he gets going, he’ll swing things in the Bobcats’ favor.” “I’m the Bobcats underdog here,” Chalamet said in his first choice, choosing the University of Ohio Bobcats over the Miami University RedHawks.

In another pick, the “A Complete Unknown” actor chose Texas over Georgia, drawing a reaction from the crowd in Atlanta.

“I go here with my film father (Matthew) McConaughey. I’m sorry to everyone here,” he said, referring to his and Texas football superfan McConaughey’s film “Interstellar,” in which McConaughey plays Chalamet’s father. Chalamet later shared a photo of himself standing next to McConaughey at the Texas-Georgia game.

The ease and confidence with which Chalamet delivered his picks impressed sports broadcasters and “College GameDay” hosts Kirk Herbstreit and Pat McAfee, who sat between Chalamet and gave him claps and high-fives as the actor went through his predictions.

Chalamet was also the subject of a flurry of social media posts expressing shock at the actor’s seemingly extensive college football knowledge.

At the end of the night, four of Chalamet’s winning picks turned out to be correct, including his tip that the University of Ohio should beat Ohio’s Miami University.

Chalamet’s highly anticipated “A Complete Unknown,” a Bob Dylan biopic, hits theaters this Christmas.
