M*A*S*H

M*A*S*H sometimes MASH, is the title of a book, a film and a TV show about a Mobile Army Surgical Hospital in the Korean War.

The books
The original book (MASH: A Novel About Three Army Doctors) was written by Richard Hooker, based on his experiences as a surgeon in such a unit.

There were a number of further books written by Hooker alone, or later co-authored with Peter Butterworth. They follow up the characters from the original book, plus a few new ones. The first few retained something of the quality of the original, but later became rather formulaic.

Some titles include:

M*A*S*H Goes to Maine

M*A*S*H Goes to New Orleans

M*A*S*H Goes to Paris

M*A*S*H Goes to London

M*A*S*H Goes to Las Vagus

M*A*S*H Goes to Texas

M*A*S*H Goes to Morocco

M*A*S*H Goes to Hollywood

M*A*S*H Goes to Moscow

All the books focus on Hawkeye and Trapper John Macintyre as the key characters.

The film
Starring Donald Sutherland and Elliott Gould, this Robert Altman film is based on the above book.

The TV show
The TV show M*A*S*H was a spin off of the film MASH. One of its noteable qualities was that it ran for eleven years while the war only lasted three. Of the three versions of the canon, the TV series is by far the most popular, and the first that comes to mind for most people when you mention M*A*S*H.

The fanfiction
Fanfiction often explores what could have been. Here those are romantic relationships between Hawkeye and BJ and between Hawkeye and Margaret. Often these stories are about set after the war when everyone went home. Fanfics are, almost invariably, based on the television series.

The authors in this fandom tend to be older than the average fanfiction writer, which results in much less Mary Sues dropping in at the 4077th. While there is more bad slash by far, however, there are still Sues.
