The storylines for the two sequels were devised by "Genisys" writers Kalogridis and Lussier. The trilogy was being planned out before "Terminator Genisys" began filming, as producers David Ellison and Dana Goldberg wanted the full storyline finished ahead of time rather than having to "figure it out as you go along," stating, "We spent a lot of time breaking that down, and we do know what the last line of the third movie is, should we be lucky enough to get to make it." Production on the sequels was contingent on whether "Terminator Genisys" would be successful; development of the trilogy stalled in 2015 after the film's disappointing box-office performance. The planned sequels were ultimately cancelled, with "Terminator 2" being removed from Paramount's release schedule in January 2016.
