The Player - I don't remember Malcolm McDowell's cameo. I did watch this, and I know that the cameos are considered one of the more amusing things about it. But it's been a long time, and as with Short Cuts I've never bothered to revisit this for some reason, and indeed I don't think I ever completed 10 whole Altman movies--M*A*S*H, McCabe & Mrs. Miller, The Long Goodbye, Nashville, Secret Honor, The Player, Short Cuts, A Prairie Home Companion. Yep, that's only 8. I do know that The Player was viewed as a significant comeback for him when it came out and it got rave reviews, as did Short Cuts, which I remember better.
I'm sort of surprised anyone wanted Cate Blanchett for a blockbuster villain character after she played arguably the lamest Indiana Jones villain. But then again we now know that Spielberg never even wanted to do the movie.
