FilmFlex, is a UK pay-per-view movie service, which is a joint venture between Sony and The Walt Disney Company.

FilmFlex makes up part of Virgin Media's "On Demand" video on demand system. FilmFlex has been available on Virgin since January 2005 and saw over 11 million films watched on demand in 2009. FilmFlex replaced Front Row which was a near video on demand pay-per-view service which was initially available on analogue cable from 1997, switching to digital when digital cable services launched from late 1999 onwards.

FilmFlex provides over 500 movies some of which are available in HD (high definition), which are available at any time for the viewer to watch when they want to. Viewers can search for a movie by title, genre, cast or director. Once a movie has been ordered it can be viewed any time within the next 24 hours before it has to be paid for again. The movie can also be viewed as many times as the viewer likes within the 24 hours for no additional cost. Once viewers are watching a movie they have full control over it by the use of pause, rewind and fast forward functions, much like a DVD.
