The Deadly Mantis (1957)
[the officers are all staring at Marge]
Dr. Ned Jackson: It looks like you don't have too many women up here, Colonel.
Col. Joe Parkman: Well, we have a little joke up here. The boys say there's a girl behind every tree. Only try and find a tree.
Dr. Ned Jackson: I'm convinced that we're dealing with a Mantis in whose geological world the smallest insects were as large as man, and now failing to find those insects as food, well... it's doing the best that it can.

Opening Narration: For every action, there is an equal and opposite reaction.
Dr. Ned Jackson: In all the kingdom of the living, there is no more deadly or voracious creature than the Preying Mantis.
Col. Joe Parkman: Maybe there's an ordinary explanation to what happened, but I wouldn't take any bets.
bus passenger: [Exiting bus in fog] You know, it's good to get home safely with all the strange things going around here.
bus driver: Oh, there's nothing to worry about, ma'am. You just be careful out there in that fog!
bus passenger: [Uncertainly] Thank you.
