All the various Bulldog Drummond movie series had run their courses by 1951; nonetheless, MGM decided to revive the property (and simultaneously liquidate some "frozen funds") with the British-filmed Calling Bulldog Drummond. Walter Pidgeon stars as novelist Sapper's soldier-of-fortune, here retooled as a respectable retired military officer. Summoned to London by Scotland Yard, Drummond is assigned to break up a dangerous criminal gang. He is aided by female undercover officer Helen Smith (Margaret Leighton), who turns out to be not much help at all. Trapped in a bombed-out building and surrounded by hulking henchmen, Drummond seems to have run out of luck. Some of the film's brightest moments are provided by David Tomlinson as a traditional "silly ass" type who is lot smarter than he seems. Bernard Lee, the future "M" in the James Bond films of the 1960s, appears as a secondary villain. ~ Hal Erickson, Rovi
