James Dickey played the sheriff in the movie version of his novel “Deliverance.”
Stephen King has played small roles in “Pet Sematary” and in the miniseries “The Stand,” among many others.
Any other examples of authors who have acting roles in movies based on their own work?
I don’t count things like Kurt Vonnegut doing an appearance in Rodney Dangerfield’s “Back to School,” or Salman Rushdie appearing in “Bridet Jones’ Diary.”
Kurt vonnegut has a very brief appearence as “sad man in street” at the end of Mother Night. IMDB lists him as appearing in Breakfast of Champions, which I haven’t seen. (Appparently it’s terrible.)
Although there are debates still about the role he played in writing many of the original stories, Stan Lee (one-time editor in chief and author for Marvel Comics) has cameoed in most/all movies based on Marvel properties.
Peter Benchley has a line or two in Jaws.
Robert Benchley was fairly successful author and and actor. He starred in a movie version of his humor article, The Treasurer’s Report.
Have you seen Stephen King in these roles? I think that really stretches the term “acted” perhaps you should just go with “Authors who’ve appeared in movies based on their books”.
John Irving has had a couple of cameo roles in movies made from his books (wrestling ref in The World According to Garp, train station agent in The Cider House Rules).
Arthur C. Clarke has a nonspeaking cameo as a man sitting on a bench outside the White House in 2010. Plus his photo is used as that of the U. S. President.
Richard Matheson appeared as a passerby who says, “Astounding” (I think that was his sole word of dialogue, maybe it was “Astonishing,” I can’t remember) in Somewhere in Time.
On the TV front, novelist Erle Stanley Gardner appeared in the final episode of the Perry Mason TV series.
