Alan Rickman returns to Broadway in the fall, when he’ll topline the world preem of “Seminar,” a new play by Theresa Rebeck.

Much-employed Off Broadway helmer Sam Gold (“Circle Mirror Transformation,” “Kin”) makes his Rialto debut with the show, about a lit-world giant (Rickman) teaching a seminar for four young scribes.

It’s fairly unusual for producers to debut a new play in a commercial Broadway run, rather than test a new work at a nonprofit theater prior to a transfer. The star casting of a well-known thesp such as Rickman, however, helps backers hedge their bets. (Last season “The Motherfucker with the Hat” preemed on the Rialto in a staging starring Chris Rock.)

Although Rickman was last on Broadway in the 2002 revival of “Private Lives,” he was seen in Gotham earlier this year in the Brooklyn Academy of Music presentation of the Abbey Theater’s “John Gabriel Borkman.”

Rebeck’s most recent Main Stem outing was Manhattan Theater Club’s 2007 production of “Mauritius.” More recently, her play “The Understudy” had an Off Broadway stint at the Roundabout in the 2009-10 season, and she’s also a writer-producer of NBC’s upcoming Broadway-centric skein “Smash.”

Jeffrey Finn (“Oleanna,” “On Golden Pond”) and Jill Furman (“In the Heights”) produce “Seminar,” targeting a fall berth at a Shubert theater to be announced.
