During the 6/5/15 TCM presentation, Ben Mankiewicz reported this was the last of the Bulldog Drummond series that John Barrymore would appear in. Mr. Barrymore's alcoholism had become so out of hand, that for this film Barrymore could no longer read lines. Even if they were written down and shown to him off camera. So he was quietly let go from the Drummond series and H.B. Warner would go on to play Colonel Neilson in the four remaining Drummond films at Paramount.
Drummond's car is a 1932 Alvis Speed SA. An example of this car, in good condition, could be worth over $100,000 in 2021. This same car can also be seen in Bulldog Drummond's Revenge (1937).

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.
Film editor Edward Dmytryk was very anxious to become a film director and approached director James Hogan and asked if he could remain on-set and observe Hogan and his technique. Dmytryk's only previous directing experience had come in an unsuccessful Poverty Row Western three years earlier (The Hawk (1935)). The veteran director graciously agreed. Afterward Dmytryk became a well-known and respected director in his own right with classics like "Murder, My Sweet," "Crossfire," "The Caine Mutiny," and "Raintree County" among his 56 films.
