Schoeffler will perform the final week of performances March 15-21, as well as a matinee on March 10, as the French lover of Marsha Mason's character.
The co-production with New Jersey's McCarter Theatre Center began its Off-Broadway run Feb. 3 and is set to open March 2 for a run through March 21.
Wintertime follows the story of a young man who prepares to propose to his girlfriend at a secluded snowbound house when he finds that his mother and her lover already occupy the cabin. As if that was not enough, the father then shows up with his boyfriend for an evening that is filled with even more surprise guests.
Schoeffler was the standby for the lead role in the recent revival of Nine. His other Broadway credits include Cyrano — The Musical, Victor/Victoria and Peter Pan.
Marylouise Burke (Kimberly Akimbo) and Christopher Denham (Master Harold...) join the original McCarter cast — replacing Lola Pashalinski and McCaleb Burnett, respectively.
David Schweizer directs a cast that also features Tina Benko, Brienin Bryant, T. Scott Cunningham, Carmen de Lavallade, Nicholas Hormann and Danny Mastrogiorgio.
