When Laura, after shooting Steele's raft, does the legwork, she goes from place to place, talking to people and making notes. In one of those little scenes she holds the notebook in her left hand and writes with her right one, then she also shakes left hands with the man - the tape was reversed.
After Laura, Mildred, and the fake Wainright hear the explosion and rush to the window to see the boat explode, the film freezes for a moment.
Laura: Wainwright's enjoying this far too much for my satisfaction.
Steele: Well, for giving us a shot at thirty thousand dollars, he can do handstands on the deck naked as far as I'm concerned.
Steele: My philosophy, Mildred, is that nothing in life is worth doing unless it can be accomplished by a shortcut.
Steele: Laura, the man's talking about twenty thousand dollars. That buys an awful lot of paper clips.
Laura: (during a car chase) Courage, Mr Steele!
Steele: Courage is not the issue here, it's horsepower! He has it, we don't!
Steele: The Wizard of Oz; Judy Garland, Ray Bolger, MGM...1939
