Sylvester Stallone on paljastanut, mitä seurauksia huippukunnossa pysymisellä oli elokuvan Rocky III kuvauksien aikana. Seurauksena oli muistikatkoksia, eikä näyttelijä muistanut edes omaa puhelinnumeroaan.
Se on tietenkin sanottava, että itse elokuvassa Rocky III Stallone on erittäin kovassa kunnossa.
"I am a coffee drinker, but I keep getting reflux, so I have to cut it down. I used to drink about 10 cups a day. Actually, I used to drink about 25 cups a day when I was doing 'Rocky 3'. My entire breakfast would be maybe two small oatmeal cookies made with brown rice and 10 cups of coffee because I wanted to keep my body fat down to 2.8%. I was forgetting my phone number. I was eating just tuna fish. My memory was shot, it was completely gone. I was getting all kinds of debilitating physical effects. But it was for the cause."
