Matsumoto's earlier film For My Crushed Right Eye contains some of the same footage and could almost be seen as a trailer for Funeral Parade of Roses, although a true trailer was also made.
The film was a major influence on Stanley Kubrick's 1971 film A Clockwork Orange.
The Plot:
This violent dramatic bloodbath concerns a love triangle in a gay bar in Tokyo. Eddie (Peter) and the transvestite Leda (Osamu Ogasawara) both have sexual designs on bar manager and drug dealer Gonda (Yoshio Tsuchiya). Gonda fears Leda will expose him to the police if he does not give in to his/her advances. When Leda commits suicide, Eddie and Gonda are free to engage in their homosexual yearnings for each other. When Gonda discovers he is Eddie's father, he kills himself with a knife. A distraught Eddie then uses the same knife to cut his own eyes out.
