In the early 1980s, SHAFT was released on tape by MGM/UA Home Entertainment. It was distributed by Publishing and Broadcasting Video (PBV).
Presumably, this was the same version for which Communications and Entertainment received an M-rating in October 1985. The running time was 97-minutes.
Warner Home Video had a DVD passed as M (Low level violence, Low level coarse language) in March 2001.
Sweet Sweetback’s Baadasssss Song
Directed by Melvin Van Peebles / 1971 / USA / IMDb
Date: 08-1971 / Rated: Banned / Length: 9159 feet / Time: 101:46 / Reason: violence and indecency
Post-November 1971 rating
Since the original refusal, SWEET SWEETBACK’S BAADASSSSS SONG has never been resubmitted.
It was due to screen in 1980 at the Adelaide Festival but was dropped following intervention by the South Australian Attorney-General, Trevor Griffin. The issue was the opening sex scene involving the director’s son, a 14-year-old Mario Van Peebles.
SBS screened it for the first time on 14 October 1992.
