A lecture on Frayn's Copenhagen.

BOMB interview with Michael Frayn.

I haven't read it yet, but The Copenhagen Papers: An Intrigue by Michael Frayn and Copenhagen star David Burke looks like fun.

... This book concerns a mysterious package Frayn received during the play's London run, from "Celia Rhys-Evans," saying that she had seen the play, and that during a stay at Farm Hall in the '60s she had found some papers written in German that must be relevant. The crumpled papers appeared to make a joke about Ping-Pong and uranium 235. In true British style, it turned out to be a hoax perpetrated by Burke, revealed by a third person just as Frayn was about to go to the papers....

(You can also buy the script, of course.)
