There’s some serious father-daughter adorableness happening at the Sundance Film Festival right now: Judd and Maude Apatow, we’re looking at you.

Maude, a 17-year-old rising star who had previously only been featured in her father’s movies (This Is 40, Knocked Up, and Funny People) and producing projects (like a guest appearance on Girls Season 4) is in Park City, Utah, appearing in her first non-Apatow-helmed film, Other People, which was written and directed by SNL scribe Chris Kelly. The drama, about family members dealing with their mother’s cancer in both heartbreaking and hilarious ways, kicked off the first night of the festival (read: a huge honor). In the film, Maude stars as Alexandra, the daughter of Molly Shannon’s cancer-stricken character, Joanne.

And Dad’s beyond proud.

Papa Apatow was by his daughter’s side to celebrate the film all night—and his beaming-father dial was turned way, way up. The pair started their evening at the Acura Studio on Main Street with an intimate dinner with the cast and crew. They didn’t separate as they munched on arugula salad with gorgonzola, beef tenderloin, and pear tarts. Later, at the red carpet at the Eccles Theater, he watched with a grin as his daughter got her picture taken in her RED Valentino floral dress in front of a pit of photographers on the red carpet. At one point, in an unprecedented move, he actually snuck behind them and took his own personal snaps, too. That’s when the photographers noticed him and gestured for him to join, which he did. After the premiere, he also tweeted his enthusiasm for the movie:

(Side note: The film was very moving, personal, and emotional, yet had many smiles and one very memorable dance sequence along the way.)

As for Maude, she smiled with Dad all night too and did so with the other family she was supporting—the one of her film—as well. “Maude is so easy to love and it was so easy for me to pretend like I was her mother because she’s just the best,” Shannon (in Kate Spade New York) told InStyle before the premiere. Maude blushed, then reciprocated. “Molly’s great,” she said. “She’s just like my mom [Leslie Mann]. And they’re both actresses!”
