NEW YORK — There was something for virtually everyone to smile about on Broadway on Tuesday after 30 of 37 shows this season got at least one Tony Award nomination. But the folks at “Once” had the most reason to celebrate.

The musical based on the low-budget 2006 film about an unlikely romance between a Czech flower seller and an Irish street musician in Dublin earned a leading 11 nominations, including nods for best musical, for both its lead actors, its book, lighting, sound, choreography and its set, which offers the audience real drinks before the show in a replica pub.

“‘Once’ constantly surprises me. I think it’s the power of the music and the storytelling that people connect with,” said John Tiffany, who was nominated for best director of a musical.

Two other big winners were Disney and the Gershwin estate: Two musicals using George and Ira Gershwin songs — “The Gershwins’ Porgy and Bess” and “Nice Work If You Can Get It” — each got 10 nominations.

And “Peter and the Starcatcher,” a play about the origins of Peter Pan co-produced by Disney Theatrical Productions, earned nine nominations, while Disney’s energetic song-and-dance musical “Newsies” got eight nods.

Christian Borle, the “Smash” star who was nominated for his hysterical performance as Black Stash in “Peter and the Starcatcher,” was preparing to go on with a big smile on his face. “It’s been an amazing day. So, really, I could get hit by a bus right now and think it was a net gain.”

Later this summer, “Once,” “Nice Work If You Can Get It” and “Newsies” will compete for the title of best new musical with a surprise entry — “Leap of Faith,” which was ravaged by critics. “Ghost the Musical” failed to get nominated in the best musical category.

The fall revival of Stephen Sondheim’s “Follies” got eight nominations, setting up a faceoff in the best revival category with “The Gershwins’ Porgy and Bess,” which Sondheim had criticized for messing with a classic.
