In the Heights, the exuberant hit new musical conceived by an actor-composer when he was in college, and with a book by a young Philadelphia playwright, received 13 nominations yesterdaytues for Broadway’s biggest prize, the Tony Award.

In a season ripe with memorable musicals, the first-ever Broadway revival of Richard Rodgers and Oscar Hammerstein’s wartime story, South Pacific, led the nominations for best revival of a musical, with 11.

The straight-play category was topped by August: Osage County, a skewering, often hilarious look at a family in crisis. The comedy/drama, an import from Chicago’s Steppenwolf Theatre,cq created buzz for the raw power of Tracy Letts’ unleashes in hisscript and the production’s exceptional acting, got seven nominations, and is considered a shoo-in for the best play Tony.

August: Osage County was named best play by the New York Drama Critics’ Circle on Monday. The group, composed of Broadway critics, also gave best-musical honors to Passing Strange, a new hip-hop show about an African American teenager who leaves California to find himself among Europe’s avant-garde. Passing Strange followed In the Heights in new-musical Tony nominations yesterday, with seven, including best book and best actor, both for a personable theater artist who calls himself Stew.

In the Heights, about the gentrification of Washington Heights, the Latino neighborhood at Manhattan’s northern tip, mixes salsa, hip-hop, rap and other musical styles, and features some of Broadway’s most intriguing dancing, for which choreographer Andy Blankenbuehler was nominated. It also received nominations for music and lyrics by Lin-Manuel Miranda, who stars and was nominated as best musical actor. He began working on the show as a student at Wesleyan University.

The script for In the Heights earned Philadelphia playwright Quiara Alegría Hudes, 30, a nomination for best book of a musical. She , which sometimes engages cast members in simultaneous individual dances,spent four years working andreworking the dialogue, while writing other plays, and has said much of the character development and plot came out of her experiences in North Philadelphia, where her parents own businesses and ran the popular El Viejo San Juan restaurant, now closed, on Girard Avenue.

Hudes was with castmembers yesterday as they performed songs from the show in Times Square for ABC-TV’s Good Morning, America, when the show’s publicist appeared with the list of nominees.

“We were like, ‘omigosh! omigosh!Oh my gosh! Oh my gosh!’ ” Hudes said, “everyone passing around the list and saying, ‘Oh, this is amazing.’

“Now I can buy a dress and not knock on wood, now I know I can go to the Tonys. I have to be honest – I’ve tried not to think about it. I was nervous about it.”

For Hudes, who lives with her husband and daughter both in New York and in Northern Liberties, In the Heights is her Broadway writing debut. “It’s so cool,” she said, “that everyone in the creative team got nominated. . . . These are the people I’d been meeting with once a week to go over a new draft of the show, for four years.” This is such a group effort, you want people to be honored for their work. It’s really a special day.”

The Roundabout Theatrecq Company’s high-tech revival of Stephen Sondheim’s Sunday in the Park With George, which examines the artistic obsession of 19th-century French painter Georges Seurat and projects it onto his progeny, received nine nominations, including best musical revival. A staging of Grease starring a couple chosen by the audience of the NBC-TV talent runoff Grease: You’re the One That I Want also was nominated for best musical revival, as was the dynamic Gypsy, which stars Patti LuPone in a career-high performance as Rose, the stage-mother who’ll do anything to see her daughters in the footlights. She was nominated for best musical actress.

In addition to August: Osage County, new works up for best play are Tom Stoppard’s Rock ‘n’ RollCQ apostrophes, which considers the fall of communism and the draw of rock music in one complicated metaphor; The Seafarer, Irish playwright Conorcq McPherson’s night of drunken, devilish mischief; and Patrick Barlow’s wildly kinetic The 39 Steps, a gag-a-minute spoof of Alfred Hitchcock’s thriller. Philadelphia’s Arden Theatre Company has acquired rights to produce The Seafarer on one of its Center City stagesnext season.

Along with In the Heights and Passing Strange, best new musical nominations went to two stage makeovers of movies: Cry-Baby, the just-opened take on John Waters’ film about 1950s haves and have-nots, and Xanadu, which turns an almost universally disliked film into a sparkling, funny stage show.

One production conspicuously absent from the best-revived play nominations – or any Tony nominations – was Tennessee Williams’ Cat on a Hot Tin Roof, with an all-African American cast led by James Earl Jones and Phylicia Rashad. The production apparently failed to move the nominators, although it is steadily drawing enthusiastic audiences. Best-revived play nominations went to Boeing-Boeing, about a traveling man who juggles girlfriends; the staging of Harold Pinter’s ode to sexual expression and repression, The Homecoming; a new Roundabout production of Les Liaisons Dangereuses; and a stylish, riveting Macbeth that came from London to the Brooklyn Academy of Music, then to Broadway.

That production stars Patrick Stewart, nominated for best leading actor in a play, as was Laurence Fishburne for his vivid portrayal of the late U.S. Supreme Court justice Thurgood Marshall in the one-man Thurgood. Other nominees are Mark Rylance (Boeing-Boeing), Rufus Sewell (Rock ‘n’ Roll), and Ben Daniels (Les Liaisons Dangereuses).

Deanna Dunagan, portraying the pill-popping, take-no-prisoners momma in August: Osage County, was nominated as best leading actress in a play; so was Amy Morton, who plays her oldest daughter. S. Epatha Merkerson, as whose portrayal of thewhose stymied wife sparked the revival of William Inge’s Come Back, Little Sheba, also was nominated, as were Eve Best (The Homecoming) and Kate Fleetwood (Macbeth).

In addition to Miranda and Stew, best leading musical actor nominations went to Daniel Evans, who plays two parts in Sunday in the Park With George; Tom Wopat in A Catered Affair; and the commanding Brazilian baritone Paulo Szot, an opera singer who fully encompasses his mysterious character in South Pacific.

In addition to LuPone, others singular performance in Gypsy earned abest musical actress nominees include are, along with Kelli O’Hara, for herwho builds a sweet, strong portrayal of South Pacific‘s love-jolted ensign, Nellie Forbush; They’re joined by Kerry Butler, playingas the wacky Muse descended from heaven to inspire a beleaguered artist in Xanadu; Faith Prince (A Catered Affair); and Jenna Russell (Sunday in the Park with George).

All productions that opened in Broadway’s 39cq theaters since the Tony Awards last June were eligible for nominations. Twenty-three theater professionals chose the nominees, and 795 members of the theater community will choose the winners. The awards ceremony, hosted by Whoopi Goldberg, will be televised live on CBS on June 15 from Radio City Music Hall.
