The First Great Train Robbery
In 1979, whilst "The First Great Train Robbery" was on general release, Butterworth was starring as Widow Twankey in the pantomime "Aladdin" at the Coventry Theatre. When the show had finished, he went back to his hotel following the evening's performance. His failure to return for the following day's matinee show caused alarm, and he was found dead in his room from a heart attack.
