I show you in less than four minutes how to get behind the Hollywood sign. Many people tried to find the way desperately. From below it is actually not possible, the closest distance is about 450ft. But using the right track through the Hollywood Hills, you can reach the sign from behind. Your reward is a distance of about 40ft to the sign and a great view over Los Angeles. The trip takes about 45 minutes and using this film you shoud be able to find the right way. Have fun!
