For the sake of list manageability and my own sanity, the list has four rules: 1. If multiple films were directly adapted from a single play, only one entry is included (with a note mentioning other adaptations). Otherwise, this list would be 3-4 times larger and consist almost entirely of adaptations of Romeo and Juliet. 2. Overlap between sources is acceptable if the penultimate source is different. Robert Wise and Jerome Robbins' West Side Story is included separately from Romeo and…

Read with notes for more information. In instances where the play's source material was also an adaptation, that information is listed back to the first known source material.

A list of films adapting stage plays which were themselves adaptations.

2. Overlap between sources is acceptable if the penultimate source is different. Robert Wise and Jerome Robbins' West Side Story is included separately from Romeo and Juliet because it adapts a stage musical based on Romeo and Juliet rather than Romeo and Juliet itself.

3. Each film must directly adapt a play, not something that was also adapted from a play. Jonathan Levine's Warm Bodies is not included because it adapts a novel which adapts a short story which adapts Romeo and Juliet.

4. Adaptations of historical events and figures are acceptable, but autobiographical work is not included unless it had been published in some format. Nearly every artistic work is semi-autobiographical to some extent and giving leeway on this raises the nearly impossible question of where the line is drawn.

I would like to give credit to Fred Beukema's list Movie to Musical to Movie Musical, which was published around the same time I began research for this list and without which I would not have found Bill Foster and Ron Field's Applause.
