I made a post similar to this, but not a poll, way back in 2008. I didn’t actually recall it, but it came up as a suggested similar topic when I started this thread. The James Earl Jones thread prompted me to mention Field of Dreams, which sent me down this rabbit hole. So, KC has been in quite a few of my favorite movies, I’m going to list just 10 of his here, plus an option if yours didn’t make it.
Bull Durham for me, and it’s not even close for me (YMMV of course).
I like Tin Cup more than I should, probably because it is in some ways similar to Bull Durham, and I have a copy of Waterworld which I watch despite Costner, rather than because of it (as I said in another thread, it’s worth the 4.99 I paid for the DVD to watch Dennis Hopper chew the scenery) as well as a copy of The Bodyguard for my trio of owned movies.
The bodyguard is for the soundtrack, which, while sappy, is a fond memory. And it’s not terrible, but KC’s role isn’t dependent on KC’s skills, almost anyone competent could have done well in the role.
I must correct myself, I also have a copy and enjoy Open Range. I find it a better movie than all but Bull Durham that I’ve watched, but I always forget it because it’s not near the top of my favorite Westerns.
So owned: Bull Durham, Waterworld, Bodyguard, Open Range
