Born in 1960 as one of the six children in his family, Neil grew up only acting in a few school plays. But the idea of acting for a living wasn't a thought that hit him before he was almost ready to graduate from college.
Firstly he did a lot of theater acting, and he has been awarded with two Jefferson Awards for excellence in Chicago Theatre. Later on he became involved in both big screen projects and small screen: movies and TV.
Many will know him as a transit cop from The Fugitive, the 1993 Oscar winner with Harrison Ford as the starring role, because of a Scrubs episode in which you can see a scene with him running through a train. But he has also been in known moving pictures like Magnolia, Mean Girls, Chain Reaction, and more.
As mentioned above, Neil Flynn appears in Scrubs. His role as The Janitor became so popular and important during the first season that his guest star position was upgraded to resident cast member.
