To honor the 100th anniversary of Eugene O’Neill’s play “The Hairy Ape,” Flock Theatre will perform the piece this weekend and next at the B.P. Learned Mission School in New London.

The show dates also coincide with the 134th birthday of O’Neill, the celebrated playwright who spent his boyhood summers in New London. (He was born Oct. 16, 1888.)

“The Hairy Ape” was an early expressionistic play by O’Neill in which Yank, a coal stoker on an ocean liner, runs into trouble with the other stokers, the daughter of an industrialist, and organized labor.

Flock says that the play “offers a dual picture: of an individual’s alienation and of the roiling social divisions of the 1920s” and that the themes resonate today.

The cast includes Alex Molina, Christie Max Williams, Eric Michaelian, Suzanne McCormack, Gary Poe, Cat McDonald, and Sarah Paprocki. Derron Wood directs.

In addition, Flock will hold a post-performance dessert reception and champagne toast this Friday in the Thames Club’s basement pub (O’Neill’s father, James, used to hang out there). All ticketholders are invited.

Proceeds from the Friday reception supports Flock’s new “I Belong” educational programs in area schools, inspired by “The Hairy Ape.”
