The production, which features real-life husband and wife Keir Dullea and Mia Dillon as Big Daddy and Big Mama, respectively, runs through Sept. 29. 

In the production from the Wellfleet Harbor Actors Theater (WHAT), Dullea — who played Brick, Big Daddy's son, in the 1974 Broadway production of Cat alongside Elizabeth Ashley and Fred Gwynne — and Tony nominee Dillon (Crimes of the Heart) are joined by Madeleine Lambert as Maggie and Steven De Marco as Brick. Elizabeth Falk directs.

"Gwynne was magnificent as Big Daddy," said Dullea in a previous statement. "He inspired me to want to play that role. His voice rings in my ears today. I'll be reaching deep to find that voice within myself."

Dullea and Dillon have been married 15 years and met while reading "Selected Shorts" for NPR. They appeared together in the tour of Deathtrap and the film "Isn't it Delicious."
