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.

Directed by: Lawrence Kasdan
Starring: William Hurt, Kathleen Turner, Richard Crenna, Ted Danson
Factual error: Under US law neither Peter Lowenstein nor Oscar Grace would be allowed any level of participation in the investigation, arrest and prosecution of Ned Racine. Both have a highly visible social relationship with him, which disqualifies them from having anything to do with a criminal case against him. In fact as soon as he became a suspect in Edmund Walker's murder they would both be officially 'warned off' - told not to contact him again for any reason.
Ned: You better take me up on this quick. In about 45 minutes, I'm going to give up and go away.
Question: If Ned couldn't open the boathouse door and got blown up at the end - how did Kathleen Turner do it and survive the explosion?
Answer: Matty had Teddy tell her how to rig the bomb with a timer. She activated the bomb, escaped in a boat on the water, leaving Ned holding the bag. But, with a good lawyer, he would have easily beat the case. Unfortunately, he confesses to his cop friend, Oscar, in the jailhouse (which might be inadmissible).
