Manhattan Theater Club has filled the final remaining slot in its 2011-12 season, skedding “Regrets,” a world premiere play from Brit scribe Matt Charman, for a spring opening.

The 1950s-set story centers on a young man who heads to a Nevada retreat for a quickie divorce and gets caught up in the era’s pervasive political mistrust.

MTC production reps the playwright’s Gotham bow. Charman’s U.K. legit credits include “The Observer,” “The Five Wives of Maurice Pinder” and “Greenland.”

“Regrets” rounds out a 2011-12 MTC lineup that also includes Broadway offerings “Venus in Fur,” “Wit” and the latest from David Auburn, “The Columnist,” starring John Lithgow. On the Off Broadway slate are Zoe Kazan’s “We Live Here” and Molly Smith Metzler’s “Close Up Space,” starring David Hyde Pierce.

Director and cast have yet to be nailed down for “Regrets,” which begins previews March 1 ahead of a March 20 opening at MTC’s Off Broadway venue, City Center.
