"It's been dawning on me slowly that for the past 35 years I have been cast against type, and I'm finally getting to do what I really wanted to do"

This quote by Leslie Nielsen speaks with the idea of being able to pursue one's true enthusiasms in life. For the previous 35 years, Nielsen had actually been cast in roles that were not always in line with his real desires. However, he has come to the awareness that he is now able to do what he really wished to do. This could imply that he is now able to pursue roles that are more in line with his real interests, or that he is now able to pursue other enthusiasms that he had actually been not able to pursue due to his previous commitments. Whatever the case might be, it is clear that Nielsen is now able to pursue his real desires and is excited about the possibilities that lie ahead.
