Baby Reindeer creator and star Richard Gadd roared back into the spotlight with his edgy 2026 series Half Man, which is as captivating and strange as Reindeer. His character, Ruben, is the hypermasculine, violent, out-of-control half-brother of a closeted and meek writer, Niall (Jamie Bell). While the two men are oil and water, they've become codependent over the years, leading to a dysfunctional relationship at a heated breaking point. Multiple actors portray Ruben and Niall as they come in and out of each other's lives over the years, including both Gadd and Stuart Campbell as Ruben, and they happen to both go shirtless! Gadd has beefed up since Baby Reindeer, now proudly sporting hulking muscles. His teen self is portrayed by Campbell, who strips to his undies for some sexy time. Half Man, full mast over here!
