Galaxy Quest, Down Periscope and Evolution. Also the original Shrek, which spoofs every Disney trope going (the sequels were awful).

Also, the only four 'Carry on' movies that directly spoof other genres: Don't Lose Your Head. Carry on Screaming, Carry on Up the Khyber and Follow That Camel.

Finally, Love at First Bite. Which spoofed Twilight before Twilight was even written!
