Scott MacArthur

MacArthur starred in the Fox series The Mick from 2017 to 2018. MacArthur was initially hired as a writer for the series. The Jimmy character was played by Nat Faxon in the original pilot for The Mick, with the knowledge that Faxon would not be able to continue in the role if the pilot got picked up to series. After offering the role to MacArthur, Fox re-shot the pilot prior to the series debut.

MacArthur has also appeared in films, such as The Diabolical (2015) and Answers to Nothing (2011), as well as numerous guest roles on television. He appeared in the 2019 Breaking Bad epilogue film, El Camino: A Breaking Bad Movie, as welder/criminal Neil Kandy.

In September 2024, he was cast in a recurring role on the superhero series Spider-Noir.

In February 2025, MacArthur was cast in Netflix series Running Point as Ness Gordon, the older brother of Kate Hudson's character, Isla Gordon.
