In an 8 p.m. Thursday timeslot that has given ABC fits, the Alphabet net will next try intense drama “Last Resort,” from an exec producer team led by Shawn Ryan (“The Shield,” “Terriers”) and Karl Gajdusek. Andre Braugher is the commander of a nuclear sub that goes rogue for the (apparent) right reasons and ends up at an island that might have been the runner-up in casting for the lead in “Lost” — perhaps not the only thing “Last Resort” has in common with that bygone hit.

The rest of the ensemble includes Scott Speedman, Daisy Betts, Dichen Lachman, Daniel Lissing, Sahr Ngaujah, Camille de Pazzis, Autumn Reeser and Jessy Schram. ABC has promised more than it could deliver on Thursdays at 8 for years, but Ryan is as good a contender as anyone to bring home a winner.
