Portland has been the setting of a number of films over the years and in 2015, Colin Firth was spotted on Portland filming scenes for The Mercy, a biopic of yachtsman Donald Crowhurst, who gave misleading reports which implied that he had sailed around the world when in fact he had remained in the Atlantic.

In May 2008 Portland Port was used as a location for Richard Curtis film The Boat That Rocked.

Portland Harbour was used as a substitute for the North Sea, from which rogue DJs played by Rhys Ifans and Bill Nighy broadcast illegally.
