Hammer Studios planned many more of the Dick Barton series. However on Saturday 9th July 1949, coming home from a cast party in Maidenhead celebrating the release of the previous film in the series (Dick Barton Strikes Back (1949)), star Don Stannard crashed the car he was driving into a tree and was killed instantly, aged 34. His five passengers (including co-star Sebastian Cabot and Mrs Stannard) were only slightly injured.
The planned sequel was to have been "Dick Barton in Darkest Africa".
Future TV and film star Patrick Macnee makes a brief appearance at the beginning of the film as the agent who is shot dead in a telephone box.
