Edward Dmytryk may have been poaching in Alfred Hitchcock territory in directing Mirage, but I can hardly see how Hitchcock could have done the film any better. In fact I'm convinced that Gregory Peck was cast in the lead on the strength of his performance in the Hitchcock classic Spellbound, the parts are so similar.
Gregory Peck when we first meet him is making his way down the stairs of a skyscraper that has sustained a blackout. As people talk to him who seem to know him he answers with the appropriate small talk, but he doesn't remember anything other than his name. At the same time, a prominent foundation leader, Walter Abel, plunged to his death from that skyscraper and of course the Peck's amnesia and Abel's death are connected. But in this case the whole point of Mirage is remembering how. And Peck better remember soon because people like Jack Weston, George Kennedy and House Jameson keep trying to kill him.
As in Spellbound, the amnesiac Peck has a woman friend trying to help him. But there was no doubt about Ingrid Bergman's loyalty to Peck in trying to unravel his situation there. Diane Baker has the same function in this film, but there is some doubt as to whose team she's actually playing on. Similarly there is Kevin McCarthy who seems a friend at first, but later on we're not so sure. McCarthy has a key role in bringing the whole affair to a climax.
The ruthless villain of the piece is Leif Erickson who started in films playing the fathead rival to whomever the hero was in a film. As he got older, directors saw greater potential in him and used him in a lot of more serious parts, mostly villainous and this one is one of his best.
Although I think the film is great, Gregory Peck kind of fluffed it off, my guess is also that his role is too much like the part he did in amnesia. But he did according to the Michael Freedland biography of Peck, recommend to Eddie Dmytryk that he cast Walter Matthau in the role of the private detective who Peck goes to. Peck also consults Robert H. Harris a psychiatrist and both the shrink and the gumshoe come to the same conclusion that Peck really doesn't want to remember his recent past, possibly because of some trauma. Matthau's role in Mirage was one of his best character roles prior to getting stardom with his Oscar winning performance in The Fortune Cookie. Harris is also quite good, in fact he's my favorite in the cast.
Although the similarities between Spellbound and Mirage are too obvious to overlook, one should not belabor the obvious. Mirage is a fine enough suspense thriller to stand on its own. And Alfred Hitchcock would not have minded being mistakenly credited with directing it.
