Body Heat (1981)

Factual error: Regardless of how bad an attorney he is, Ned Racine must surely know that his acquittal for murder is a shoe-in. It's very doubtful that the prosecution would have even held out for remand in his case, and in fact they probably would not have even charged him in the first place. The fact that his fingerprints are on Edmund Walker's glasses is irrelevant. He and Racine were seen in public together, notably in the restaurant, and he freely admits to being in Walker's house. He could have handled Walker's glasses on any one of these occasions. The conversation Racine has with Ted about building the firebomb cannot be used in court, as Ted fires Racine as his lawyer at his second meeting; everything from the first is covered by attorney-client privilege. Maddy obviously isn't around to give evidence, and the yearbook entry Racine finds throws suspicion on her (and away from Racine) immediately. There are no witnesses and no forensic evidence, in fact there is nothing to support the prosecution case except a vague suspicion based upon his having had an affair with the widow-to-be. No court in the US would entertain the case for a minute.

Ned: You can stand here with me if you want but you'll have to agree not to talk about the heat.
Matty: I'm a married woman.
Ned: Meaning what?
Matty: Meaning I'm not looking for company.
Ned: Then you should have said I'm a happily married woman.

Trivia: Teddy Lewis tells Ned that "Matty" had him show her how to rig up a explosive with a delay to a door. So in theory Matty could have opened the door and escaped unscathed.

Question: Maddy pulls up to the house in her dead husband's Cadillac right around the time Ned was supposed to be at the boat house. Why would she be driving his car when at that point in time, she is supposed to be Mary Ann Simpson, her real identity? Ned was supposed to be dead at that point. The boat house could have blown up as she arrived and the fire dept. called by a neighbor would be on its way?
