Directed by: Sylvester Stallone
Starring: Sylvester Stallone, Burt Young, Carl Weathers, Talia Shire, Hulk Hogan
Visible crew/equipment: Just before the second fight with Clubber and just after the pre-fight brawl, when the camera switches to the shot of Rocky and Apollo you can see a director's chair at the top left of the screen with "Mr. T" written on it. (01:22:50)
Apollo Creed: See that look in their eyes, Rock? You gotta get that look back, Rock. Eye of the tiger, man.
Trivia: Mr. T was chosen for this role by Stallone himself - he spotted Mr. T in a "world's toughest bouncer" contest (which Mr. T won). What sold Stallone was Mr. T's snazzy dressing, no-nonsense attitude and spectacular lingo. Apparently, the line that solidified him on the idea of hiring T was Mr. T's answer to the question "how do you handle potential troublemakers?". Mr. T had his head shaved bald at the time, and his answer was "I tell dem fools that mah patience is as long as the hair on mah head." He was hired almost instantly. The role in Rocky III got him the spot in the A-Team, and the rest is history...
Answer: A detached retina can be fixed with surgery, and since Rocky is now well-off, we can assume he did just that.
