From IMDB:

After his lover rejects him, a young man trapped by the oppressiveness of Edwardian society tries to come to terms with and accept his sexuality.

From Kanopy you can stream this 2 hour 20 minute vintage British film made by Merchant Ivory and  based on the 1971 novel Maurice by E. M. Forster

34 years ago some very young but now well-known British actors made what  has been called Ivory’s best film. In 1987 it got rave reviews and awards everywhere except England.  In the Wikipedia article about the film, the director James Ivory is quoted as saying:

… in England, where almost every important film critic was gay, they came out against the film. Their reactions to it were extraordinary! You’d think that they would have been supportive, but they were afraid to be supportive.

Despite those actors being so young, it is easy to recognize Hugh Grant, James Wilby, Rupert Graves,  Judy Parfitt, Ben Kingsley and others.

If there is a secondary theme, it is the strict division between the upper and  servant classes.
