Movies That Used Shortened Versions of Their Source-Book's Title

If nicknames count, the play turned (almost too grainy to watch in the only copies I’ve seen) movie The Persecution and Assassination of Jean-Paul Marat as Performed by the Inmates of the Asylum of Charenton Under the Direction of the Marquis de Sade was marketed by its nickname of Marat/Sade. That title appears on the DVD in fact (with the full name in small print further down).

Anna and the King of Siam became Anna and the King.

Simon Birch is shorter than the book’s title of A Prayer For Owen Meany, and much shorter than the true title of The Hack who Wrote “Grumpy Old Men” Takes a Big Dump on the Work of One of America’s Greatest Novelists and then Rubs it All Over the Screen.

You do N RC, the short book (which makes the movie look like a two-reel comedy!) was also called Double Indemnity.

I have seen the book referred to, in reviews and on the title page of the screenplay, as Double Indemnity, Or Three of A Kind. Was it perhaps the lead story in a collection?

Sir Rhosis

and then became “The King & I”

The Book of Daniel by E.L. Doctorow was filmed as Daniel.

Goodbye, Picadilly; Hello, Leicaster Squre became Hitchcock’s FRENZY. (I may have the book name reversed, I’m going from memory.)

A Cry in the Dark was the movie; the book was Evil Angels.

None of these fit the premise. None of them are shortened versions of the source material’s title; they’re all just re-namings.

…but Simon Birch would have been called Owen Meany if John Irving wasn’t so disgusted with Mark Johnson’s screenplay.

Does [October Sky count? Probably not. It was an anagram of Rocket Boys, the book it was based on.
