The Ringer is a 1952 British mystery film directed by Guy Hamilton and starring Herbert Lom, Donald Wolfit, Mai Zetterling, Greta Gynt, William Hartnell, and Denholm Elliott.

It was Hamilton's directorial debut and the third English-language sound version of Edgar Wallace's 1929 play based on his 1925 novel The Gaunt Stranger.

Complicating matters is the arrival of elderly Aberdonian criminologist Dr. Lomond and Meister's plan to take his secretary for himself rather than let her abscond with her fresh out of prison lover John Lemley, even preparing to leave with his British passport and her German identity card.

The settings and dialogue are theatrical and a good cast, notably the hard-working William Hartnell, can do little to bring the story to life.

"[5] Allmovie wrote, "Donald Wolfit, whose legendary thespic excesses were later fictionalized in the stage play The Dresser, is perfectly cast as a vengeance-seeking master of disguise".
