Frequently considered to be the feature film debut of Gordon Jackson (who portrayed Alastair 'Jock' MacFarlan, 19th Fusiliers). However, although Nine Men (1943) was released approximately one year after this film, it was in production and completed before this one, so both have a claim to being Gordon Jackson's film debut.
A ten year old Anthony Ainley has a small uncredited role in this film. 39 years later he would become better known as 'The Master', the nemesis of television's Doctor Who, a role he played from 1981-1989.
