A lot of classic movies are themselves remakes of even older movies, like The Wizard of Oz, Ben-Hur, or The Ten Commandments
A few horror movies come to mind like The Fly, Invasion of the Body Snatchers, and John Carpenters The Thing

Planet of the Apes reboot trilogy
Definitely this
If you want to get technical the Lord of the Rings trilogy could be considered a reboot of the Baksi and Rankin/Bass cartoons.
