Identity Unknown is a 1960 British drama film directed by Frank Marshall and starring Richard Wyler, Pauline Yates and Patricia Plunkett.

The Monthly Film Bulletin wrote: "A complicated and episodic blend of sentiment and suspense, which fails in the latter aim through the confusion and number of its miniature dramas.

"[3] Kine Weekly wrote: "The tale has everything except comedy, but uneven acting and treatment makes it difficult to grasp, let alone follow, its many threads. ...

The picture or, to be more precise, gallery of vignettes keeps the survivors' identity a secret until the end, yet fails to build up suspense.

Pauline Yates is a likeable Jenny; Richard Wyler registers as John; and Valentine Dyall's not too bad as Ambrose, but the others aren't much cop.
