Factual error: The issue of "Guideposts" shown by Crane's interviewers is from the early '90s.
Factual error: Crane's daughters play with a bent-armed Barbie doll; all such dolls of that era had straight arms.
Continuity mistake: Bob puts his hand on his wife's shoulder, in the next shot, it is by his side.
Factual error: Crane's kitchen phone in the '60s has a modern (at least 1970s) modular cord on the handset.
Character mistake: Although great care was taken to duplicate Bob Crane's distinctive hairstyle for Greg Kinnear, Bob Crane's hair was actually parted on the left. The makeup department for this film parted Greg Kinnear's hair on the right, producing a mirror-image of Bob Crane's hairstyle.
Deliberate mistake: Although much of Auto Focus revolves around the 1960s hit television series "Hogan's Heroes," the producers of this independent film could not work out a licensing agreement with CBS regarding the famous "Hogan's Heroes" theme music. As a result, the familiar "Hogan's Heroes" theme music is entirely absent from Auto Focus, replaced with contrived theme music that isn't even remotely similar to the original.
