FilmFour has started shooting Jerry Rothwell’s documentary pic “Deep Water,” about the disastrous 1968 round-the-world yacht race.

Pic is one of four new projects from Channel 4’s film unit scheduled to shoot this summer, including Kevin Macdonald’s “The Last King of Scotland,” Penny Woolcock’s “Mischief Night” and the latest Shane Meadows pic “Oi! This Is England.”

“Deep Water” is produced by Jonny Persey and Al Morrow of APT Films, and will be released in the UK by Pathe, which is also handling international sales.

“Last King of Scotland,” co-financed by Fox Searchlight’s UK venture DNA Films, stars Forrest Whittaker as the notorious infamous dictator Idi Amin, and James MacAvoy as a young doctor who gets drawn into his web.

Upcoming releases for FilmFour in 2005 include “The League of Gentlemen’s Apocalypse,” Billy O’Brien’s Irish horror pic “Isolation,” Keith Fulton and Louis Pepe’s faux-doc “Brothers of the Head,” James Marsh’s Cannes entry “The King,” Annie Griffin’s “Festival” and the doc “Sisters-in-Law,” also premiering in Cannes.
