One of those it-seemed-like-a-good-idea-at-the-time movies, 1981's Sphinx was one of those pictures that looked so much more promising on paper than it did on screen: based on a novel from the author of Coma, which had been a smash hit a few years earlier, directed by Franklin J. Schaffner, who was responsible for Patton and Planet of the Apes, and dealing with the search for a lost tomb and a deadly trade in stolen Egyptian antiquities, it sounded like it should have made for a smart and glossy thriller. It certainly managed the glossy part, with glorious Scope photography of most of the major ancient Egyptian tourist attractions from the pyramids of Giza to King Tut's tomb as well as a cast headed by Lesley Anne-Down, Frank Langella, Maurice Ronet and John Gielgud. It was just the smart bit it never really managed. When she's not telling everybody she meets that she's an Englishwoman who now lives in Boston to explain away her accent, Down's crop-topped Egyptologist reacts to most situations by screaming, even when it would be infinitely safer to keep her mouth shut, and it's pretty obvious that neither of her leading men is entirely to be trusted even if they're not quite as obvious stage villains as John Rhys Davies' smuggler, who actually kicks a dog in his opening scene just to underline what a swine he is.
Yet throughout there's the suspicion that, faced with a plot that could have done service in a 1930s programmer despite a few modern retouches, Schaffner and co. have decided not to take it entirely seriously even if they are playing it with an admirably straight face. John Byrum's screenplay certainly seems tongue-in-cheek at times: aside from playing on tourist stereotypes in scenes with Saeed Jaffrey's tour guide, a scene where she hides under the bed from an intruder in her room is played for comedy of embarrassment rather than suspense, one truck chase is filled with throwaway sight gags and the location of the tomb itself, hidden in plain sight, could definitely be said to be taking the urine. Take it on that level and keep your brain switched in neutral for its 117-minute running time and it's entertainingly silly and resolutely undemanding old-fashioned hokum. Expect anything more, and disappointment is inevitable.
