As of this writing [June 2018], the film has finally been put out on DVD, in all-region release in Australia. The case cover of the DVD has a still pic of the nude Flanagan from the famous masturbation scene, unlike the American MCI Universal VHS cover in the 1980s in which Flanagan has her nightgown on.
The movie is based upon a stage play conceived by Fionnula Flanagan, who did two years of research before writing, producing and starring in the stageplay and the later screen production. The play was directed by Burgess Meredith, and premiered Aug 1977 in Costa Mesa, CA, and ran off-and-on for five years domestically and internationally. On the day the show came to Emporia, a small Kansas town, a local Baptist minister denounced Flanagan in the Emporia Gazette as "the whore of Babylon." His feelings of moral outrage--prompted by the undeniable fact that she played an X-rated Molly--took up at least half a broad-sheet page.
"As you might imagine, once that article appeared it was almost impossible to buy a ticket," the Dublin-born actress recalled in an interview at her airy, rustic home in Beverly Hills. "Everybody came out to see the show. People were hanging out of the rafters."
This film is based on James Joyce's Ulysses and shows real, on camera masturbation by Fionnula Flanagan, the main actress.
