God this movie is truly awful. I can't believe people worked and paid to make this stink bomb. Cavemen becoming fighter pilots with 1 week of flight simulator. Ridiculous aliens, retarded plot. etc. A good laugh though.
Its ripped off an older movie... There was a discusion about it in the Psychedelic forum (old forums)
Battlefield Earth is one of those movies that's such a torture to watch, it automatically clears the universe of any bad karma you have. So if you want something good to happen to you, just punish yourself by watching this abomination.
