The Razor's Edge is an adaptation of W. Somerset Maugham's 1944 novel The Razor's Edge. It stars Bill Murray (who also co-writes), Theresa Russell, Catherine Hicks, Denholm Elliott, Brian Doyle-Murray and James Keach. It was directed and co-written by John Byrum. This marked Murray's first starring role in a dramatic film, though Murray did inject some of his dry wit into the script. The book's epigraph is dramatized as advice from the Katha Upanishad: "The path to salvation is narrow and as difficult to walk as a razor's edge."
