'Reckless Youth' scene
Anyone notice that the Doctor's office, the party apartment and Mary's living room are actually all the same set? They just moved furniture around and redressed it slightly (carpet etc).
Also of note is the segment with Herb Vigran (the Agent): the background music was used on the 50's Superman TV show in which Herb appeared numerous times as a somewhat comical bad guy. There are a couple other unrelated scenes in the movie which too use music from this show...turns out this incidental music was sold in "packages" at affordable prices. Because of this you'll hear it in many low budget serials and early TV shows.
Sorry for clogging your brains with such flotsam, now you know a little of MY pain LOL
