The Celluloid Closet is a documentary film directed and written by Rob Epstein and Jeffrey Friedman. The film is based on the 1981 (revised 1987) book of the same name written by Vito Russo, and on previous lecture and film clip presentations given in person by Russo 1972-82.
In 1963 (probably July, though some sources place the dates in May or June), Eric Dolphy recorded some sessions in New York with producer Alan Douglas, the fruits of which were issued on small labels as the LPs Conversations and Iron Man. They've been reissued a number of times on various labels, occasionally compiled together, but never with quite the treatment they deserve (which is perhaps why they're not as celebrated as they should be). In whatever form, though, it's classic, essential Dolphy that stands as some of his finest work past Out to Lunch.
