Dan Stevens and Rebecca Hall attended the University of Cambridge at the same time as Eddie Redmayne and Tom Hiddleston.

Conan O'Brien and CNN boss Jeff Zucker lived in the same dorm while they were students at Harvard. But they were more rivals than friends: Jeff was the president of the university's daily newspaper, the Harvard Crimson, and Conan was the president of the college's humor magazine, the Harvard Lampoon. According to Deadline, Conan once spearheaded a prank on the Crimson, stealing all the copies of the newspaper before it could be distributed. Jeff retaliated by calling the cops, and he was even on hand to confront Conan face-to-face as the funnyman was arrested. "He only forgave me when I gave him 'The Tonight Show,'" the former NBC exec said in 2005. But that forgiveness may not have lasted long: NBC fired Conan from the coveted late night gig after less than a year.

Though the "Crazy Ex-Girlfriend" creator (who posted these selfies on Instagram in April 2016) studied theater and the "Broad City" star and co-creator majored in psychology, they became roommates shortly after graduation, which makes us think they probably crossed paths from time to time during their days at NYU.
