"My own personal taste in films as a member of the audience was not completely in line with films I was doing"

Rick Moranis is referring to the reality that his own personal taste in movies as an audience member does not always align with the films he is making. This could be due to the reality that he is a star and is often required to handle roles that might not necessarily be his very first choice. He may be needed to handle functions that are not in line with his own personal taste in movies, however he still puts his best shot into the functions he handles. This quote shows that Moranis is an expert star who wants to handle roles that might not be his very first choice in order to earn a living. He is also going to put in the effort to make certain that the movies he is involved in are of the highest quality.
