Sometimes a revival can not be good.I know that from personal experience,In 1935 a play opened in NY and had a nice run.
For a reason that I have no idea why I decided to write an updated version and got permission of the family of the late playwright to adapt a play based on the original.The play opened in 1964 and closed the same night.My Director had success with Broadway and Off Broadway productions.My cast was comprised of basically unknowns ,perhaps that was the problem.
