Dune
David Lynch was not impressed with how the producers squashed his artistic vision for the movie. The fans of the novel turned the tide, however, and made it into a cult classic. Sting’s presence in the movie might have also helped things along.
Office Space
Office space was a difficult movie to market. It fell into a genre of its own and ended up failing on release. When it hit the video store, things started to heat up and word got around. Anyone who could relate to sucky office work found the movie hilarious and turned it into a cult classic.
