WASHINGTON — Fasten your seat belts and get ready for your closeup.

Sixty-five years after those quips in “All About Eve” and “Sunset Blvd.,” the line between Broadway and Hollywood has never been more blurred — and that’s great for show business.

Not only did the Broadway-themed “Birdman” win this year’s Oscar for Best Picture, a number of movie stars are nominated for Tonys on Broadway’s biggest night Sunday at Radio City Music Hall.

Bradley Cooper, Helen Mirren, Bill Nighy, Carey Mulligan, Ken Watanabe and Elisabeth Moss are all nominated for stage performances this year, while the nominated plays evoke fond movie memories: “An American in Paris,” “The King and I,” “On the Town” and “The Elephant Man.”

This symbiotic relationship is nothing new. Broadway has long provided Hollywood backdrops, from Busby Berkeley’s kaleidoscopes in “42nd Street” (1933) to Bob Fosse’s pill-popping addictions in “All That Jazz” (1979) to Charlie Kaufman’s surreal obsessions in “Synecdoche, New York” (2008).

Perhaps the most famous crossover happened in 1964, when Hollywood refused to cast Broadway’s Julie Andrews as Eliza Doolittle in the film version of “My Fair Lady,” opting for Audrey Hepburn. Andrews got the last laugh by taking the lead in “Mary Poppins” and beating Hepburn for the Oscar.

The Andrews-Hepburn dilemma taught us a valuable showbiz lesson: that Hollywood and Broadway can be mutually beneficial. Just ask Anna Kendrick, who is currently riding a stage-to-screen wave with “The Last Five Years” and “Into the Woods,” or Idina Menzel, whose “Wicked” popularity reached new heights after John Travolta’s “Adele Dazeem” botch at the Oscars.

No one knows this phenomenon better than nine-time Tony-winner Tommy Tune, who joined WTOP to discuss Sunday’s Lifetime Achievement Award at the Tonys.

“We did not have theater in Houston where I grew up … so my inspiration came from the movies,” Tune tells WTOP. “Fred Astaire and Gene Kelly, they were the guys for me.”

Tune says his favorite Kelly film is “Singin’ in the Rain” (1952) and his favorite Astaire film is “Swing Time” (1936), though he also enjoys “Top Hat” (1935) and “A Damsel and Distress” (1937).

“I was a really skinny kid and everybody made fun of me ’cause I was so skinny,” Tune says. “(Fred Astaire) looked really skinny to me, and he wore these great clothes, and I knew that he was a swell, elegant guy and I went, well, that’s for me.”

Tune will never forget the time he got to meet his idol.

“He came backstage after seeing a show I was in, and these are the first words he said to me: ‘You are a tall son of a b****.’ He said it! And then he laughed. He couldn’t believe he said it.”

The 6-foot-6 Tune also got the chance to dance with Astaire’s legendary co-star Ginger Rogers, performing a fox trot at the Waldorf Astoria in New York City.

Such are the perks when you’re a nine-time Tony winner about to earn a Life Achievement Award.

“It’s sort of a completion of a life,” Tune says. “They tell you that from the time you say your name, you have 90 seconds to make it to the stage and say your ‘thank yous’ before they start to get the hook and pull you off. So I’m trying to distill 55 years of show business into a 60-second speech.”

While Tune is guaranteed his tenth award Sunday, Victoria Clark is seeking her second Tony with “Gigi,” which had its pre-Broadway debut at the Kennedy Center with Vanessa Hudgens.

Clark joined WTOP back in February before she even knew she would be nominated for a Tony:

Clark’s “Gigi” cast is just one of the many to perform live on Sunday. The cast of “The King and I” will perform a Rodgers and Hammerstein medley, from “Shall We Dance?” to “Getting to Know You,” while the cast of “On the Town” will perform classics from their Leonard Bernstein, Betty Comden and Adolph Green score, including “New York, New York.”

Kristin Chenoweth and Alan Cumming will take over the hosting reins from Hugh Jackman, who hosted last year’s Tonys just weeks after his summer blockbuster “X-Men: Days of Future Past” (2014). The three previous years were hosted by Neil Patrick Harris, who won a Tony last year for “Hedwig and the Angry Inch” the same year he seared the silver screen in “Gone Girl” (2014).

This increase in Hollywood starpower may be responsible for Broadway doing record business. Last week, The Broadway League announced that revenue and attendance both hit record highs for the third straight season, grossing $1.36 billion with attendance up 7.3 percent to 13.1 million visitors.

So if you’re still somehow on the fence about whether to watch the Tonys on Sunday, it’s time to do what so many movie stars have already discovered — it’s time to go back to Broadway.

The 69th annual Tony Awards air Sunday at 8 p.m. on CBS. See below for the full slate of nominees:
