Calling Bulldog Drummond is a 1951 British crime film directed by Victor Saville and featuring Walter Pidgeon, Margaret Leighton, Robert Beatty, David Tomlinson and Bernard Lee.

After three robberies are pulled off with military precision, Inspector McIver asks Hugh "Bulldog" Drummond to give Scotland Yard a hand.

He agrees, though he very reluctantly accepts Sergeant Helen Smith of Special Branch as his partner, believing that women are not cut out for that sort of undercover work.

Gunns' attraction to Smith and carefully planted evidence showing "Joe Crandall" and "Lily Ross" to be criminals themselves enables the pair to infiltrate the gang.

Gunns' girlfriend Molly convinces him to go ahead with the latest planned robbery, enough to set them up for life, despite the police having been put on alert by Drummond.
