TS: Just thought I'd point out that you misspelled his name in the title.
My list:
The Untouchables (1987)
No Way Out (1987)
Revenge (1990/I)
JFK (1991)
Open Range (2003)
I've yet to see Mr. Brooks but I do eventually plan on seeing it.
And while JFK is one of my favorites of his, I liked it a lot more before I found out that Oliver Stone was a lying ignoramus. Now I just like it because I thought Costner actually acted well (shocking, I know) and because of how well the rest of the ensemble cast performed.
The Untouchables is still by far the best film he acted in, although funny enough, his performance is probably the weakest element of the film
