1 visible crew/equipment mistake - chronological order
Directed by: James Goldstone
Starring: Henry Fonda, Richard Widmark, George Segal, Timothy Bottoms
Plot hole: When the bomber is surrounded at the end he gets shot in the leg but manages to get away from all of the police that were surrounding him. They were literally an arm's length from him.
Fran: Harry?
Harry Calder: Mmh?
Fran: If you're trying to kill us, at least let me put on some lip gloss.
