Chris Blackwell's Palm Pictures has sold US theatrical, non-theatrical, video, TV and other ancillary rights on its prison drama Lockdown to Columbia TriStar Home Entertainment. The picture, which was produced and financed by Palm Pictures and jointly made with No Limit Films and Burg/Koules Productions, chronicles the brutal prison experiences of four men who are wrongly convicted for a drive-by shooting. It stars Richard T Jones, whose credits include Event Horizon and The Wood, and Master P, who starred in Foolish and I Got The Hook-Up. Lockdown was directed by John Luessenhop in his feature film debut.

Karol Martesko-Fenster, head of film at Palm Pictures, said in a statement: "Columbia TriStar Home Entertainment already has a rich and compelling roster of films and Lockdown will be right at home in their high calibre collection." Palm Pictures was founded in 1998 as an integrated audio-visual entertainment company that develops, produces and acquires music, film, videos, animation and visual art for distribution across multiple platforms.
