As reported by our sister site Deadline, Walsh has landed the recurring role of Shane Muldoon, who is described in the breakdowns as (the yet-to-be-cast) Eddie Heffernan’s criminal boss, though you’d never suspect it from his curated demeanor and calm, assertive intelligence. “Whether fly fishing or cracking down on loose elements of his criminal enterprise, there’s an ominous edge to Shane’s charming manners,” reads the descrip.
The Western drama’s upcoming Irish mob storyline was first teased in TVLine’s Inside Line column.
In addition to his turn on CBS/A&E’s Unforgettable, Walsh’s previous TV credits include NCIS: New Orleans, Nip/Tuck, Everwood, Brooklyn South and Gabriel’s Fire.
Having made its post-A&E debut on Netflix last September, Longmire was renewed for a fifth, 10-episode season in October.
