Robert Walker started out as a member of that generation of young actors being pushed as romantic leading men (Van Johnson, Peter Lawford, etc.). I never really cared for him in that role, in movies like The Clock with Judy Garland or whatever movies he made with June Allyson. In fact, the only time I really liked his performance was in Strangers on a Train, which was probably the kind of role he should have been playing all along. It was his next-to-last movie. His last was My Son John, playing another Bad Boy but this time in a bad movie that Helen Hayes's overacting made even worse. Walker died before the movie was finished, forcing a rewritten ending patched together with some recorded dialogue he'd finished and even some footage from Strangers on a Train. But Strangers is the movie he'll be remembered for, and that's as it should be.
