LOS ANGELES: Boy mega band One Direction's new film is set to top this holiday weekend's North America box office, in the latest British invasion, an expert said Friday.

"One Direction: This is Us," which has also just opened in Britain and much of Europe, will likely depose Oscar-tipped civil rights epic "Lee Daniels' The Butler" in the number one spot over the three-day Labor Day weekend.
The movie, by Oscar-nominated director Morgan Spurlock, made $2.7 million on opening Thursday evening alone, preliminary figures show.
"The British Invasion seems to be upon us again. And by us, of course, I mean gaggles of tween girls," said Jeff Bock, analyst at box officer tracker Exhibitor Relations.
He did point out that the Labor Day weekend, the last of the summer season, is traditionally one of the slowest periods of the year at the box office.
