This Is It pulls in more than $US100m 

The Michael Jackson concert film This Is It has crossed the $US100 million mark at international box offices as it enters its second weekend in theatres.

The studio behind the movie, Columbia Pictures, says it has grossed $US144 million worldwide, including $US44 million from the United States and Canada.

That is more than double the tally of receipts for 2008's blockbuster concert film Hannah Montana/Miley Cyrus: Best of Both Worlds, a movie some box office watchers had used as a benchmark for This Is It.

Outside of North America, the biggest theatrical markets through Thursday night were: Japan with $US18.2 million, Britain with $US11.1 million and Germany with $US8.9 million.

This Is It, distributed by Sony Corp-owned Columbia, was produced from footage of Jackson rehearsing for a series of comeback concerts in London in the final weeks before his June 25 death from an overdose of powerful medication.

The movie opened on October 28 and originally was planned to play for just two weeks, but Sony extended its run.

The film is now slated to run until early December in the US and Canada.
