The only time in the series that Jonathan changes on-screen from an animal (black panther, in this case) back into a human.
Laura Cushing's sole acting credit. It is unknown what became of her, but she also has 1 producer credit for 2015.
J.C.'s animal metamorphoses: hawk (shown); panther (J.C. is seen transforming from animal back to man); and dolphin (not shown).
This time, Jonathan keeps in his downstairs glass enclosures: a wallaby, an ostrich, a tiger, and a couple of lionesses. The ostrich is seen in the far left enclosure, a few frames after J.C. was seen placing the injured wallaby there. The glass partition had remained open while the professor had attended to the animal's paw, and no ostrich was then seen.
At 37:26 this is the actual New York Police Headquarters at 1 Police Plaza in Lower Manhattan.
Gloria Stuart: Screen legend, whose career spanned 1932 until 2004, appears for barely 2 seconds as an extra digging in a dumpster, when J.C. is chasing the wolf girl down a back alley.
