I was really into Grease [1978], too, when I was a kid—like reenacting “Hopelessly Devoted to You…”

That movie put me in a good mood! #GreaseSingAlong

Did you ever wear your superfan costume for Halloween? What was your favorite Halloween costume?A couple of years ago, I was Sandy from Grease for Halloween—the version of Sandy at the end of the film.

Whoa. I wasn’t expecting that.” I love surprising people with a present of a gift or a stage performance or anything. I love John Travolta, who came off that Kotter show. Nobody knew he could dance or do all of those things. He is like—boom. Before he knew it, he was the next big Brando or something.

Favorite Movies: Grease and Forrest Gump

Was there a movie you loved as a kid that you’re embarrassed by now? Grease. [Laughs]

Niall’s favourite movie of all time is Grease. He’s also a fan of horror movies.

It’s hilarious, but it’s just a really short thing. Grease, because Grease is great: it’s a musical about the 1950s, but made in the 1970s and everybody’s 30. Love it.

Grease. Every word. I loved ”Grease,” which isn’t even in the original musical.
