During the dream sequence, all of the scenes are actual clips from previous movies where circumstances prevent the marriage of Drummond to Phyllis Clavering.
The plot ultimately derives from Conan Doyle's The Musgrave Ritual.
This is one of 8 Bulldog Drummond adventures produced by Paramount in the late 1930s, and sold to Congress Films (II) in mid-1954 for re-release; Congress redesigned the opening and closing credits, in order to eliminate all evidence of Paramount's ownership, going so far as to even alter the copyright claimant statements on the title cards; Congress, in turn, sold the films to Governor Films for television syndication. Along the way, Paramount, having disowned the films, never bothered to renew the copyrights, and they fell into public domain, with the result that inferior VHS and DVD copies have been in distribution for many years, from a variety of sub-distributors who specialize in public domain material.
John Howard (Captain Hugh C. 'Bulldog' Drummond) and H.B. Warner (Colonel Nielson) were in Horizons perdus (1937) two years earlier.
This film received its initial television presentation in Philadelphia Thursday 20 January 1955 on WPTZ (Chanel 3); it first aired in New York City Monday 7 February 1955 on WCBS (Channel 2).
