When Mo Brings Plenty first arrived on the “Yellowstone” set, his character Mo didn’t have an official name. Even in the show’s credits, the actor is listed simply as Rainwater’s Driver up until Season 2, Episode 6. This changed after Brings Plenty did a scene with Gil Birmingham one day and Birmingham used his real name — Taylor Sheridan liked it and decided to keep it in. “During this particular scene, we were doing it and he said my name, and it happened to be our best take,” explained Brings Plenty in an April 2022 interview with Cowboys & Indians magazine (via Outsider). “It was the most natural.”
Speaking to The New York Times, Birmingham remembered how it was ultimately Taylor Sheridan who made the call to keep Mo’s name in the long run. “When Mo is out and about, it’s pretty funny because people tend to call you by your character name, and it happens to be his real name,” Birmingham said. “There’s no distinction there for fans.” With each new season of “Yellowstone,” Plenty and Birmingham’s relationship gets stronger and stronger, which has led to great chemistry both on and off-screen. “Our brotherhood just, it continues to grow,” Brings Plenty told Cowboys & Indians. “And I have a lot of love and respect for that guy.”
