Maya Hawke Supports Brother Levon Hawke in His Directorial Theater Debut in N.Y.C.

Levon Hawke's directorial theater debut Picture Day was a family affair!

Levon's first major project as a writer and director at the Coffey Street Studio had a few famous faces in the audience over the play's final weekend in Red Hook, Brooklyn, as it headed. Ahead of the Oct. 5 performance, Levon, 22, posed for a picture with his sister Maya Hawke on the play's set and wrapped her in a big hug.

Their parents, Ethan Hawke and Uma Thurman also made an appearance. Ethan, 53, posed for a picture in matching shirts with Levon. An insider tells PEOPLE that the Dead Poets Society actor enjoyed the play so much that he saw it three times and brought his mother Leslie to a September show.

Thurman, 56, meanwhile, "gave her son lots of love," while attending Picture Day on Oct. 4, the source adds. "Levon helped determine where she should sit. During the play, Uma was laughing during some points, very focused and leaning forward, intensely listened throughout," they said.

The insider continues: "She was very low-key and humble and recognized it was Levon’s moment to shine. The play got a standing ovation at the end. She came back for closing night on Sunday."

Richard Linklater, Levon's godfather, also flew out to see one of the September performances.

Channing Tatum and Zoë Kravitz were among the crowd on Sunday, Oct. 6. Levon previously worked with Kravitz, 35, on her directorial film debut, Blink Twice.

Picture Day, which was written and directed by Levon, "delves into the secrets we keep and the reasons behind our silence," according to an official synopsis.

"Set in a mundane afternoon in a shared living room, the play follows five roommates as they navigate pseudo-family dramas, sexuality, identity and the complexities of modern male friendships."

The artwork for the show also had a sweet familial connection to those who worked on Picture Day. One of the posters for the show was done by Maya, while a painted mural displayed outside the show's venue was done by one of the actor's, Booth McGowan’s sibling, Teddy.

A source tells PEOPLE that Levon was "so passionate, dedicated and hands-on" with the play's run.

He "always arrived early each day and mingled with guests before and after the show," they added. "He truly enjoyed the whole experience and was very proud of what they accomplished."

Picture Day stars McGowan, Ian Edlund, Dante Billups, Rocco Gagliarducci, Ari Dalbert and Natalie Austin.

Picture Day, which was presented by Quick & Dirty Theatre Company, and produced by Lisa Long Adler, ran from Sept. 20 to Oct. 6. Though the cast and crew are taking a break, they're looking forward to doing an extended run of the play in the spring.
