Ken Jeong became “that” guy this year. Y’know, the guy you keep seeing in a bunch of movies but you don’t know his real name. Ken Jeong made a huge splash in the surprise summer hit, The Hangover, when he jumped out of a car’s trunk in his birthday suit. He kept on rolling with roles in The Goods: Live Hard, Sell Hard, All About Steve, Couples Retreat and a co-starring role as the cantankerous Senor Chang in NBC’s new show Community. He already has a full slate of work in 2010 and the future keeps looking brighter. This is pretty incredible for a guy who gave up medicine to pursue a career in comedy and acting. Ken was a doctor in residency down in New Orleans, but he decided to give it up to go to Hollywood. How many Korean parents would’ve rolled their eyes if their sons or daughters said that they were going to Hollywood after having gone through medical school and residency? Ken defied a parent’s logic and believed in his comedic abilities. Now he’s “that” guy that cracks people up in the hilarious character roles he plays. What Ken Jeong showed us was that even in Hollywood, you can still make it even without looking like Brad Pitt. As long as you have dedication and talent, the dream is possible. There are many kids out there who are doing what they’re parents want them to do because it’s the most conservative route. Ken just showed us that you can follow your passions and beat the odds, and that’s why he’s #5 on our list of top ten most influential Korean-Americans in 2009.
