Quick Scoop on Penny’s Age

Most discussions of the film treat Penny Johnson as being the same age as Johnny Castle, who is 25 during the summer of 1963 in the story. Because Penny is his long‑time professional dance partner working the same resort circuit, sources that break down the characters’ ages state that Penny is also meant to be around 25 in the film’s timeline.
