You may not have the unlimited funds and resources to help you get the look you want, unlike some of these actors and movie studios, but you can still make some drastic changes in your own life. I hate to put too much emphasis on appearance since looks are not synonymous with health, but I am always impressed when I see people make amazing changes to their physique.
If you need motivation to get in shape, just get cast for a role in a Hollywood movie as a bodybuilder or model, then give yourself 6 months to physically prepare for the part. If however, you are like 99% of the population then you will have to just keep plugging along with the rest of us.
It is their day job so I guess with all that support it would happen quickly for them ..foe example Biggest Loser .. I wonder if any used drugs to enhance look? like Steroids?
He's a beast in that movie.
