Sundance darling “Another Happy Day” enjoyed a hearty New York welcome at Monday’s Sunshine Landmark Theater bow.

Julian Schnabel, in paint-splattered pants, came out to support star Ellen Barkin and writer-director Sam Levinson. “I’ve known Ellen since before she was a waitress and before I was a cook,” quipped Schnabel, who said he is putting his own film helming plans on ice for a while. “I think the movie is brilliant. I was very impressed.”

Guests cabbed it across town to the after-party at the Top of the Standard. The film’s 19-year-old standout, Ezra Miller, could even catch a glimpse of home across the Hudson River. “If you look over at that clock tower, my parents live right behind that,” said Miller, pointing toward Hoboken.

A number of revelers from the nearby Council of Fashion Designers of America Awards crashed the “Happy Day” fete, including Amanda Seyfried, Olivia Wilde and DJ’s Theophilus London and Jordan Watson, who commandeered the turntables.
