16. Chris Pratt
Starting his career as a comedic goof, Chris is today one of Hollywood’s most famous hunks. Whether he is running through the jungle in Jurassic Park, or fighting off aliens in the Guardians of the Galaxy, Chris has shown off a fabulous new look. Not only did he give up on beer for 6 months, but he also sought the assistance of a nutritionist and personal trainer to gain a ridiculously chiseled figure for his new roles.
