'Kingsman' sequel to come?

A sequel to "Kingsman: The Secret Service" is reportedly in the pipeline, following the film's box office success.

The blockbuster, directed by Matthew Vaughn and starring Colin Firth, just topped $400 million at the global box office and Fox is interested in a follow-up, according to The Wrap.

While there has been no announcement by the studio or a timetable just yet, the tip came from "individuals with knowledge of the project."

The original film is based on the comic book "The Secret Service" created by Mark Millar and Dave Gibbons and held the line -- to the tune of $41 million -- against "Fifty Shades of Grey" on its opening weekend in the US.
