Stage Fright (1950)

Det. Insp. Wilfred 'Ordinary' Smith: Look here you don't look like an irresponsible imbecile, why behave like one. What do you mean letting your daughter get mixed up in a business like this, what sort of a father do you think you are?
Commodore Gill: Unique. Quite unique.

Trivia: Alfred Hitchcock's cameo can be seen 39 minutes into the movie as a man on the street turning to look at Eve as she rehearses her scripted introduction speech to Mrs. Inwood.
