Dylan O’Brien is bringing the heat to the press trail. The 34-year-old actor gave "Heated Rivalry" heartthrob François Arnaud a shoutout on Hits Radio UK. The two shared a scene together in 2025's "Twinless." O'Brien also had nothing but love for his "Send Help" co-star Rachel McAdams. Check out their most viral interview moments here, from BBC1, "The Tonight Show," "Royal Court," and more — and even an adorable sit-down with O'Brien's dog, Tony.
