Rob Schneider - 27.18
Eddie Murphy - 33.1
Adam Sandler - 39.23
Steve Buscemi - 41
Sylvester Stallone - 42.7
Will Ferrell - 47.31
Jim Carrey - 51.91
Frank Welker - 52.82
Samuel Jackson - 58.47

Tom Hanks - 62.91
Morgan Freeman - 63.42
Bruce Willis - 63.9
Harrison Ford - 67.2
John Ratzenberger - 70.91

I don't think averaging the scores for actors works nearly as well for determining who you think is the best though, since they only have so much control over the film, and some people (see John Ratzenberger) have a lot of insignificant parts in really good films.
