What is Sylvester Stallone's first name?

Story on Stallone's "mumbling" is parts of his face are paralyzed including the lower left side by and inside his mouth. This was from a misuse of foreceps when he was born that severed a nerve. The man has still done pretty well for himself.

A very good action star but sometimes has inaudible words in his dialogues.

Unkind remarks making fun of people without knowing the facts … karma

His mother was a big influence on his life,like her he had plastic surgery,his mother and Chers mother were big friends

Player #4047702, he unfortunately sustained an injury at birth which causes him to mumble.

Wonder why he never used his first name of Michael?
