This 94-minute Imax documentary by Stephen Low (1991) has the same nonaesthetic features of other films in this formatmost notably a TV-like lack of precise composition necessitated by the curved screenbut its subject, the risky Canadian-American-Russian expedition to pick over the wreckage of the Titanic, has an inherent fascination and haunted poetry that triumphs over the sometimes hokey, often trumped-up presentation; at times the film becomes a kind of undersea 2001. Oddly, the crew participants are encouraged to relate to the camera like actors and some of the camera angles suggest a fiction film (significantly, storyboards are alluded to in the final credits). But a judicious combination of period photographs (some genuine, some composite), a contemporary interview with one of the few living Titanic survivors, and views of the ship’s remnants two and a half miles below the ocean’s surface give this the curious, paradoxical feel of a scientific ghost film.
