Think that John Travolta's swinging strut from "Saturday Night Fever" was original?
Think again, says the nimble-footed star whose moves in movies have made him as famous as his acting.
In an interview with "Good Morning America," Travolta said that Fred Astaire had once asked him where he had gotten that famous walk, which is featured in the opening of the '70s classic.
"That walk down the street in 'Saturday Night Fever' was not unlike his walks in some of his movies," Travolta said.
"And he wondered where I got that from. And I had gotten it from my neighbor -- the neighborhood strut in my town of Englewood, New Jersey."
Travolta says he loves family, friends and adventure. His latest role in "Wild Hogs" lets him have all three.
"Wild Hogs" is a tale of bonding among four friends, each facing his own personal midlife crisis. Travolta plays a down-and-out baby boomer with some dark secrets.
"It's four guys who hang out on the weekends with their motorcycles. But during the week, they're professionals," Travolta said, describing the movie.
"And my character has a couple of secrets that he wouldn't dare tell his buddies, but it motivates this trip. And if women were to take that same trip, that secret would be out before they left."
Travolta said that he and his co-stars personally revved up for the road trip. "I would say that 95 percent of the footage [is] us really on our bikes doing it," he said.
It's a part that's far removed from his next role, playing the hilarious mom in the film version of the Broadway musical "Hairspray."
Travolta acknowledged that he had a newfound admiration for women who wear girdles.
"I have a new respect for women on every level," Travolta said, adding that if he thought wearing women's clothing was challenging these days, he couldn't imagine how his mother had pulled it off.
The part taught him that "women have a lot of power."
"Everyone wanted to flirt with me," he said, laughing.
Though Travolta will always be remembered for his performances in "Saturday Night Fever" and "Grease," he feels that he's really cemented his success in the last few years.
"It's been a good decade," he told "GMA."
"Something about arriving at a place in your mind where you feel like it's all icing now," he said.
"You can kind of almost retire into ease about your career and about your choices and you about your life."
And there's a lot for him to look forward to. Travolta said that he and his wife, actress Kelly Preston, were planning to have a third child.
"We're not pregnant yet but we're planning to start this summer, and that will probably be our last child," Travolta told "GMA." "But we are looking forward to having another."
Their son, Jett, is 14, and their daughter, Ella Blue, is 6.
"Oh, I would have had five or six if, if we could have," he said. "It's just that having two careers, it wouldn't have been very fair to you know, try to juggle five or six children. In my neighborhood in New Jersey, the smallest family was us at six children."
With a growing family, a beautiful wife, and a great career, it's a good time for Travolta.
"It's a time to savor," the star said.
