He should have left it alone.
Alfred Hitchcock made a scary movie based on the same work which, at least, had thousands of live birds attacking humans.
This one act play had sound effects along with films of birds at either side of the stage. Not the same effect!
It also opened with a number of very brief scenes followed by blackouts which were more annoying than anything else. It purports to detail the last people left on earth after being birded to death.
Duh!
The cast included Stevie Ray Dallimore, Sasha Diamond, Kathleen McNenny, and Rocco Sisto. It was directed by Julianne Boyd.
Go see the movie!
