7. The Room
Does this really need to explained to you? In case your life isn't fully complete and you don't know what The Room is, do yourself a favour and go hunt down a copy. It is truly something to behold. Although the chances are that you have heard of it as the film has garnered such a massive cult following. Quite often considered one of the worst movies all time, it is the guilty pleasure of many. Small cinemas will show the film on a semi-regular basis and it will always draw a crowd. The film is such an oddity not due just to its terrible script and film-making technique but also because of its creator, sometimes human-being Tommy Wiseau. The Room lends itself to being a musical due to its melodramatic story and dramatic narrative twists. Find me a person who wouldn't love to see "You're tearing me apart Lisa" in song form, and I will show you a liar.
Songs: "Oh, hi Mark!" "You're tearing me apart Lisa" "Cheep cheep cheeeep" "Oh, hi Doggy."
