Ms. 45 (aka Angel of Vengeance) was directed by the often controversial and provocative Abel Ferrara, best known for films like The Driller Killer, King of New York, and Bad Lieutenant. It stars Zoë Tamerlis Lund.
The film was inspired by 1973's Thriller - A Cruel Picture and 1974's Death Wish. It was critically maligned on its theatrical release, but is now highly regarded among fans of exploitation cinema. It was acquired by Alamo Drafthouse Films in October 2013 and remastered in HD from the original negatives. The distributor released the film on Blu-ray, DVD, and digital copy in March 2014.
