Jan. 16 (UPI) -- The Criterion Collection announced its April titles on Friday. New additions to the collection include 4K UHD of three John Singleton films and a Monty Python Classic.

John Singleton's Hood Trilogy includes 4K UHDs of his 1991 debut Boyz n the Hood, 1993 follow up Poetic Justice and 2001 film Baby Boy. It releases April 28.

The late Singleton supervised and approved Boyz's transfer before his 2019 death. He had recorded audio commentaries for all three films, which are included.

New bonus features include a conversation between filmmaker Ryan Coogler and Poetic Justice actor Regina King, a documentary on Singleton's process and audio interviews with Baby Boy stars Taraji P. Henson and Tyrese Gibson.

Boyz n the Hood depicted gang violence in South Central Los Angeles and, along with the success of New Jack City, precipitated a wave of inner-city films from Black filmmakers in the '90s. Singleton's Best Director Oscar nomination made him the youngest ever nominee in that category at the time.
