In one of the biggest casting coups for Fox this season, the network has tapped British writer-actor Nick Frost (Hot Fuzz, Paul) as the lead opposite Justin Long in comedy pilot Sober Companion. Written/exec produced by David S. Rosenthal & Jennie Snyder Urman, Sober Companion centers on Robert (Frost), a charming, but self-destructive attorney who finds his world turned upside down when a court-appointed sober companion (Long) takes control of his life. Frost’s Robert is intelligent, driven and an addict. So drunk that he does a faceplant in court, he is assigned a sober companion for the next 90 days, and must either stay away from everything he deems to be fun, or lose his job and probably his liberty. This marks the first American TV gig for Frost, who signed on for the role after lengthy courtship. The actor, repped by UTA, Think Tank Management and UK’s Hamilton/Hodell, was recently seen in The World’s End alongside his long-time collaborator and friend Simon Pegg.
