The article on the Yahoo webpage states that the bidding for the rights to this video, as a potential future movie, went up to $30 million. I have a hard time believing the bidding would be this high.
Not to take anything away from the video— it is amazingly well done for such a low budget production. The special effects would be amazing at 10 times the stated cost, i.e. $3000.
However, the concept is not exactly new. Alien life forms/robots coming to earth and destroying a city has been done in “War of the Worlds,” “District 9,” “Cloverfield,” and “Transformers.” Why would someone bid so much for concept that has been done repeatedly?
