I skipped reading The African Queen entry because I haven't seen it. In my defense, when I was a child, it was on our Beta cassette that also featured The Ewok Adventure, and after a plethora of mornings having to fast forward past it, I accidentally trained myself to avoid it on a physiological level. Time to revisit it.
As for Cuckoo's... man the thing I always remember, other than this being one of the first "real" movies I appreciated (notice my Ewok Adventure childhood above) is how great Brad Douriff was and is. Between this movie, Exorcist 3 and Two Towers, he's one of those guys that I really wished had reached the A-list. Based on the ending and on the bizarre recent defenses of shock therapy, I don't think it's in any danger of being remade.
