Age: 33

WWE superstar John Cena’s in-ring career should live long and prosper, considering that professional wrestling allows men to keep getting their faces mashed for as long as they can stand. Seriously, Ric Flair is over 60 years old and he’s still going semi-strong. So there’s really no need for Cena to make any more box-office-poison movies, like the charisma-free action flick 12 Rounds or last year’s stillborn family film Legendary. The one-time rapper (notice how we didn’t use “MC”) has the dramatic range of a statue and his action hero presence is non-existent. Just pray that he says goodbye to Hollywood before he makes a buddy cop pic with fellow muscle-bound non-actor 50 Cent.
