There will be some special Anniversaries this month, but for now...
10 Years Old This Month
School of Rock - Jack Black conning a classroom of children to put on a rock band is about a million times better than it sounds; these kids can play!
Brother Bear - Only mentioning this because it's a Disney Animated Canon film. It's one of my least favorites, mostly because it's so disjointed (the middle feels like an entirely different setting than the beginning and end), but it was a lot better than I expected it to be when I finally gave it a chance.
20 Years Old This Month
Demolition Man - I only saw it once, and I remember very little about it. However, any film that gives us a platinum blonde Wesley Snipes and an eerily prophetic "Politician Schwarzenegger" deserves to be mentioned.
Fatal Instinct - Woefully underrated parody film directed by Carl Reiner pokes fun at the kind of early 90's thrillers suggested in the title. Armand Assante is a comedy genius as lawyer/cop Ned Ravine. That's right: Armand Assante.
30 Years Old This Month
Never Say Never Again - Only saw this Bond film once, and it struck me as a ripoff of Thunderball. However, it was Sean Connery returning to his most beloved (and ironically his most personally hated) role after vowing never to come back. That's worth a mention here.
The Dead Zone - Christopher Walken in a Stephen King film. Why has this not happened again? Plus, Martin Sheen as a politician is hilarious in hindsight.
The Right Stuff - Never seen it, but everybody and their mother parodies it, so it deserves a nod.
