Bulldog Jack (released as Alias Bulldog Drummond in the USA) is a 1935 British film produced by Gaumont British, directed by Walter Forde, and starring Jack Hulbert, Fay Wray, Ralph Richardson and Atholl Fleming. The film was followed by many others involving the story of Captain Hugh 'Bulldog' Drummond; however, because of the various production companies involved, the actor playing Bulldog was frequently changed. It premiered at the Tivoli Theatre in London on 15 July 1935 and reached the US in September the same year, renamed Alias Bulldog Drummond. Bulldog Jack includes action set in a fictional London Underground station of Bloomsbury. Plot Bulldog Drummond (Atholl Fleming) is injured when his car that has been sabotaged is involved in a crash. When Jack Pennington (Jack Hulbert) agrees to masquerade as the sleuth, he is enlisted to help Ann Manders (Fay Wray) find her jeweller grandfather who has been kidnapped by a gang of crooks who want him to copy a valuable necklace they want to steal. Their plan backfires in the British Museum and the film climaxes in a chase on a runaway train in the London Underground. The London Underground as a Key Element A fictional closed Tube station (Bloomsbury) is featured as an important part of the staging of the film, being part of an intricate hideaway for the bad guys. The Underground becomes a key element in the film when the trail "Bulldog" and his assistant are on leads them to the boarded-up street entrance of a closed "Bloomsbury" station; the dapper detectives in tophats and tails ride the Tube circuit back around to the nearest station to the closed one, and then sneak onto the tracks headed to the closed platform. Part way there, a train appears down the tunnels and the men hastily climb onto the tube walls and lay flat, only to see the train disappear one car after another, switching to another Tube line. In a short but memorable scene, "Bulldog" turns a table upside-down and rides the long spiral staircase all the way to the bottom, passing two crooks on the way, and sliding across the platform and tumbling onto the tracks. The film's smashing climax is on a runaway train in the Tube, and throughout the scene the point of view is from the front of the train. In all, Bulldog Jack shows the basic appearance of the Underground in the
