From the Movieweb article:
Not only did Netflix drop Kevin Spacey from House of Cards in what perhaps was supposed to be its most important season to date in terms of bringing the story to its close, the streaming giant also canceled Spacey's Gore Vidal biopic titled Gore. Netflix disclosed its $39 million loss with the fourth-quarter earning report released on Monday. Netflix claimed they had an 'unexpected' charge for 'unreleased content' they have 'decided not to move forward with.' At this time, it's unclear what could happen to Gore, or if it will ever be released.
