Isle of the Dead is a 1945 American horror film directed by Mark Robson and made for RKO Radio Pictures by producer Val Lewton.

They discover the crypt despoiled; hearing a woman singing on the supposedly uninhabited island, they set out to find her.

They also find retired Swiss archeologist Dr. Aubrecht (Jason Robards, Sr.), his Greek housekeeper Madame Kyra (Helen Thimig), British diplomat Mr. St. Aubyn (Alan Napier) and his pale and sickly wife (Katherine Emery), her youthful Greek companion Thea (Ellen Drew), and English tinsmith Andrew Robbins (Skelton Knaggs).

Aubrecht apologizes for his part 15 years before in inspiring local peasants to rob graves for valuable Greek artifacts.

In the interim, after Karloff had recovered from the surgery but before the cast of Isle of the Dead could be reassembled, he and Lewton made The Body Snatcher.

The film had a troubled production, and the central female character of the original script (named "Catherine") was deleted entirely from the tale.

Leigh Harline's score makes use of another work inspired by Böcklin's painting, Sergei Rachmaninoff's tone poem, "Isle of the Dead".

Tedious, overloaded, diffuse, and at moments arty, yet in many ways to be respected, up to its last half-hour or so; then it becomes as brutally frightening and gratifying a horror movie as I can remember."

[3] Leslie Halliwell gave it two of four stars: "Glum, ghoulish melodrama with some neatly handled shocks; quite different from any other horror film.
