More manga/TV/Movies:
Urusei Yatsura

Lupin III
You’re Under Arrest
One could include Ranma 1/2 but I wouldn’t say that the movies were all that famous/successful.
Lassie, Tarzan, The Little Mermaid and The Many Loves of Dobie Gillis all deserve consideration, some of them with big asterisks. “The Little Mermaid” originated as a short story in an anthology, became a successful Disney movie and a reasonably popular Disney Channel cartoon. Dobie Gillis was a book of short stories about Dobie and company, became a moderately successful Debbie Reynolds film and a beloved sitcom (It was also de facto adapted as Scooby Doo, Where Are You?). Tarzan was the subject of scads of novels and films of varying degrees of popularity. While there has never been an outrageously popular Tarzan TV show (Most versions lasted one or two seasons; one version lasted three), cumulatively, all the versions have had as many episodes as Law & Order TOS. Lassie Come Home began as a short story and then a novel, begat many many movies and several TV series, one of them quite successful. The novel isn’t taught in any lit classes, but it had something going for it, I’d say.
In the Heat of the Night was successful in all three media.
The Six Million Dollar Man also deserves some consideration. It began as a mid-level SF novel, Cyborg by Martin Caidlin. It was a very popular TV movie (a format that thrived in the 60s and 70s, but not so much since) and series, under the better-known name. Jim Carrey was briefly attached to new movie based on the concept.
Doug Bowe beat me to Sherlock Holmes, dammit.
I know Little House on the Prairie and its progeny started as books and became a TV show… was it ever a theatrical movie? Wiki says no.
Casablanca was a movie and, much much later, a short-lived TV show, but I don’t think it was ever a book.
Elmore Leonard’s novel Out of Sight became a movie and then a short-lived TV show called Karen Sisco.
I’m not sure that Shepherd did much more than inspire The Wonder Years, but several of his stories were turned into TV specials, including Ollie Hopnoodle’s Haven of Bliss and The Great American Fourth of July and Other Disasters. Shep is my spirit guide.
Harry Potter. (Except for the TV show part.)
Hornblower,series of books,an old movie then a very,very good tv series a few years ago,watched an episde the other night;undated and excellent .
Michael Walsh, best know as a theatre critic and biographer, wrote “As Time Goes By” a novel based on Casablanca.
Ed McBain’s 87th Precient books were turned into several movies and a 1960’s TV series.
I, the Jury -> I, the Jury -> “Mickey Spillane’s Mike Hammer”
No, but it made it to the stage in 2008, with Melissa Gilbert in the role of Ma.
