Sylvester Stallone

Expelled from 14 schools for antisocial and violent behavior before he was age 13.
Birth complications, caused by forceps, resulted in paralysis of the lower left side of his face, manifested by a perennial snarl and slurred speech.
Les sacrifiés (2010) opened at number one at the U.S. box office with a first weekend gross of $35 million. This makes Sylvester Stallone the only person in Hollywood history to have starred in films that have opened atop the box office charts over five consecutive decades.
Stallone claims to have been able to bench press 385-400 lbs (174.6-181.4 kg) and squat 500 lbs (226.8 kg) in his prime. While in a bench pressing contest with former Mr. Olympia Franco Columbu, he severely tore his pectoral muscle and needed over 160 stitches on it. This is why one half of his chest is more veiny than the other.
At age 15, his classmates voted him the one most likely to end up in the electric chair.

Once in one's life, for one mortal moment, one must make a grab for immortality; if not, one has not lived.
That's what Rocky (1976) is all about: pride, reputation, and not being another bum in the neighborhood.
I'm not handsome in the classical sense. The eyes droop, the mouth is crooked, the teeth aren't straight, the voice sounds like a Mafioso pallbearer, but somehow it all works.
[Explaining to The New York Times how he wrote the script for Rocky (1976) in three days] I'm astounded by people who take 18 years to write something. That's how long it took that guy [Gustave Flaubert] to write "Madame Bovary". And was that ever on the best-seller list? No. It was a lousy book and it made a lousy movie.
[In 1976, after completing production on Rocky II - La revanche (1979)] But there'll never be a "Rocky IV." You gotta call a halt.
