But what do we know about Brian Geraghty, the actor? Let Outsider fill you in.
First, Geraghty says he doesn’t mind being known as the weirdo truck driver from Big Sky.
“My girlfriend and I have been together for a good amount of time because of the pandemic and I haven’t met some of her friends yet,” Geraghty said. “Their first impression of me is Ronald on ‘Big Sky.’ My best friend called me and said, ‘When does ‘Big Sky’ come back? Man, you’re so crazy!’
“It’s fun to get feedback like, ‘You’re so creepy’ or ‘I feel bad for you,’ ” he said “That’s all of the things we’re going for.”
In real life, Geraghty isn’t so creepy, although he has occasionally played those kind of characters.
He’s 45 and has been acting since 1999, when he was on an episode of Law and Order. He also was in two episodes of Law and Order, Special Victims Unit.
