Ethan Hawke proudly walks with his daughter Maya on his arm ahead of special screening of his HBO Max documentary The Last Movie Stars in NYC

Ethan Hawke has slipped into promo mode for his latest project: the new HBO Max documentary The Last Movie Stars.

The acclaimed actor put on his director's hat to help tell the story of the decades-long romance and partnership between Paul Newman and Joanne Woodward.

And on Sunday he arrived with his daughter Maya Hawke on his arm for a special screening at Film Forum, a non-profit movie theater in the Downtown neighborhood of Greenwich Village.

Ethan, 51, arrived to the cinema with his daughter Maya Hawke, who's a rising star in the field of acting in her own right, 

In a sweet gesture, the pair were seen holding hands as they walked along the last block or two of the bustling streets.

Beaming with pride, the four-time Oscar-nominated actor flashed a big smile decked out in a gray suit and a white dress shirt, which he wore unbuttoned at the top and without a tie.

He also donned a pair of black sneakers and had his short salt-and-pepper hair slicked back off his face, while sporting a manicured goatee.

Maya, 24, appeared to be equally proud to be on her father's arm dressed in an all-dark blue denim ensemble consisting of capri-style jeans that fell to around her ankles.

The outfit also included a matching denim jacket, which she wore over a red and white-patterned sweater with a v-neck, and a backpack over her left shoulder.

She rounded out her overall look by wearing a pair of black leather boots, and her blonde tresses styled just past her shoulders with a heathy dose of volume and a part in the middle. 

By the time the father-daughter duo made it out front of the theater they would soon be separated, with Ethan seemingly being whisked away to do some media commitments.

Maya, whose mother is actress Uma Thurman, looked to be ushered past the line of people that were already gathered outside of the cinema.

With The Last Movie Stars, the Realty Bites star chronicles Newman and Woodward's relationship through a series of previously unpublished conversations. 

The interviews were originally meant for Newman’s memoir, a project that was ultimately put on the back burner and ultimately scrapped, according to Indie Wire.

Newman would go on to destroy those tapes of their conversations, but transcripts were saved and used to tell their story in the documentary by using some of the biggest stars past and present.

Along with the Newman and Woodward, themselves, the cast features the likes of Martin Scorsese, Sally Field, Melanie Griffith, Sydney Pollack, Sidney Lumet, Karl Malden, Elia Kazan, Gore Vidal and Jacqueline Witte, among others.

Breaking the mold on Hollywood relationships, the Newman and Woodward union resulted in them working side-by-side on a number of films and projects, all while being married for more than 50 years.

Their final screen performance together was in the cable miniseries Empire Falls in 2005.

Newman passed away in September 2008 at the age of 83, while Woodward is still thriving at the age of 92. 

The Last Movie Stars begins streaming on HBO Max on Thursday, July 21.
