It's not one of his greatest films by far but the on-screen chemistry between Clint Eastwood, Donald Sutherland, James Garner and Tommy Lee Jones in "Space Cowboys" was really fantastic.

I just watched that one again recently Panzer. Its a fun movie. I think my favorite part is the slightly blue, black and white opening with Spanish guitar intro and X-plane flight.

Also the music from Honkytonk Man is great.
