Originally recorded by Tears for Fears, “Mad World” was covered by Michael Andrews and Gary Jules for the movie Donnie Darko. Here’s Gollum singing it. But it’s not just a cover, it’s Gollum singing about stuff that happens in Lord of the Rings to the tune of the song. Pretty creative if you ask me. But it’s not the first time! You may remember the same guy doing a song from Les Misérables. But what is up with the dude in the background?
