A film whose creators insisted was mostly improvised took the award for writing, something even credited scribe Ring Lardner, Jr., was surprised by:
The winner is the only one based on a work I've never been exposed to. The original MASH is a novel credited to Richard Hooker, the joint pen name of former military surgeon Dr. H. Richard Hormberger and journalist w.C. Heinz. The 1968 best-seller was followed by a series of sequels and inspired a stage play, a television series, and, of course, the movie. But I've never read it! I've read the play andf watched the show, but those are my only other MASH frames of reference.
The other nominees? I know them. I own copies of both Airport and Women in Love and read the original stage versions of I Never Sang for My Father and Lovers and Other Strangers in high school. Did the movies honor the source material? Who cares, it's cinema, they need to do their oWn thing. Did they accomplish that? Let's see!
