By December 2013, there were plans for "Terminator Genisys" to be the start of a new trilogy of films. In September 2014, Paramount announced release dates for the two "Genisys" sequels: May 19, 2017 and June 29, 2018. "Terminator Genisys" producer David Ellison described the film and its intended trilogy as standalone projects based on Cameron's original "Terminator" films. Ellison said "Terminator Genisys" is neither a sequel or a prequel to the previous films, saying "For us this is Terminator 1, this is not Terminator 5". The sequels to "Genisys" were tentatively known as "Terminator 2" and "Terminator 3". The two sequels were to be filmed back to back during nine months of continuous shooting.
