Although the investigation that is the focus of the play resulted in formal charges being brought against Furtwängler, he was eventually cleared by the tribunal. The original production starred Daniel Massey and Michael Pennington. Massey won the Laurence Olivier Award for his role as Furtwangler. When the play transferred to Broadway the following year Ed Harris took over the role of the American Colonel, and Massey repeated his award winning role.
