“Untraceable” topliner Diane Lane joined co-stars Colin Hanks, Billy Burke and Joseph Cross for the pic’s bow Jan. 22 at the Pacific Design Center’s Red Seven.

In the film, Lane plays an FBI agent hot on the trail of a serial killer who dispatches his victims in gruesome ways live on the Internet.

“There are 300 million streamings a day on the Internet and 9 billion a month, so the FBI knows it has a virtually unstoppable tiger by the tail,” said director Gregory Hoblit. “But they’re getting better all the time at tracking people and one of the reasons I wanted to make the movie is to show that at the end of the day, the FBI will get your ass.”
