Continuity mistake: When a particularly unfit Rocky runs up the steps at dawn, it obviously takes a long time, as when he reaches the top and we go to a different shot, it's a lot lighter. When returning to the previous angle, it gets that little bit darker again.
Trivia: Adrian's hesitation to kiss Rocky in his apartment after their date together wasn't originally scripted that way; Talia Shire was suffering from the flu during filming, and she was afraid of getting Sylvester Stallone sick. What resulted ironically was a better acted scene than was originally anticipated.
Question: In the movie Rocky, porno actress Jean Jennings is listed in the credits on numerous websites, but I can't place or recall her in the film. According to information and bio info on her, she was married to Joe Spinell, who played Rocky's friend and employer in the film. Was she in Rocky? If so, in what scene?
