Scott MacArthur, actor and staff writer on The Mick, is taking on double duty, joining the cast of Fox’s upcoming comedy series in a recurring role.

Created/written by John and David Chernin, The Mick stars Kaitlin Olson, who also co-executive produces, as Mickey, a brash, two-bit hustler from Rhode Island who has spent her entire life shirking any semblance of responsibility. Not without her charms. Mickey’s smart, fun, and despite all appearances, her head’s always in the game. She just needs a big win. That win kinda, sorta comes true when Mickey must assume guardianship of her wealthy sister’s three high-maintenance and ill-parented children: Sabrina (Sofia Black D’Elia), Chip (Thomas Barbusca) and Ben (newcomer Jack Stanton).

MacArthur will play Jimmy, Mickey’s degenerate on-again, off-again boyfriend. Once Mickey takes guardianship of her spoiled nieces and nephews, he sees himself as a lottery winner adjacent. The role is currently recurring with potential to turn into a series regular. Interesting note – we hear Nat Faxon actually played the part of Jimmy in the pilot. Faxon shot the scenes as a favor, as he was a series regular on Married at the time, and producers knew the role would have to be recast if the pilot was picked up to series. MacArthur will re-shoot those scenes in the pilot, and appear in the second episode.

A relatively new writer/actor, MacArthur hails from Improv/Olympic and the Second City Theatre in Chicago. He’s repped by Haven Entertainment, The Cartel, UTA and attorney Todd Rubenstein.

Production on The Mick, produced by 20th Century Fox TV, begins next month for a midseason premiere.
