A sequel, "The Denham Studio Mystery", was mooted by Thorold Dickinson but never made. It was planned that it would incorporate footage shot by Josef von Sternberg for his aborted film I, Claudius.
The football match from which the main action sequences were taken was between Arsenal and Brentford, and took place on Saturday 6th May 1939 with The Bees playing in a a special striped kit to simulate The Trojans. This turned out to be Arsenal's last home game before the outbreak of the Second World War. (Closer shots feature the Oxford and Cambridge Blues as the Trojans.)
The Gunners/Trojans replay kicks off at 3pm on Wednesday 26th April (dating the film to 1939), with the original match therefore presumably being held on Saturday 22nd April.
