John C. McGinley calls his Brooklyn Nine-Nine police union president character "Archie Bunker meets Yosemite Sam"

The A.V. Club

"It was too delicious of a character to pass up,” McGinley says of playing Frank O’Sullivan, the head of the patrolman’s union, who was added to the final season so that Brooklyn Nine-Nine could tackle the post-George Floyd world. “This guy only has to see blue, that’s the only color he sees, that gives so much fuel to Raymond Holt (Andre Braugher), Rosa, and Jake," says McGinley, who considers co-creator Dan Goor the Norman Lear of his generation. Since the character is a blend of Archie and Yosemite Sam, McGinley crafted Frank to be someone with extremely animated hand gestures. “I wanted to show this guy wants to keep delivering for his union," he says. "It’s not enough for him to just speak the words, he has to illustrate exactly what he is talking about.”
