Courtesy of Deadline it appears Gabriel Luna, who recently starred as the Ghost Rider in Marvel's Agents of S.H.I.EL.D., will join Deigo Boneta in the forthcoming new Terminator movie. According to the report Luna has been cast as an unspecified model and/or series of Terminator, with Boneta likely playing a key figure in the human resistance. In Deadlines article, they also revealed that the role of Dani Ramos, a reportedly integral role in the new Terminator movie has finally been successfully cast with Columbian actress Natalia Reyes taking on the role. Luna, Boneta, and Reyes will join returning stars Arnold Schwarzenegger and Linda Hamilton in the forthcoming movie, which contrary to the claims of some news outlets is not a reboot of the franchise but a direct sequel to 1991's Terminator 2: Judgment Day.
With the new cast, Columbian Reyes (pictured below), Mexican Boneta, and Luna (pictured above), who is of Mexican heritage, it would seem to suggest that the setting of the movie may be moving away from its traditional locale of Los Angeles. If, as Hamilton's return would seem to suggest, Sarah Connor's death to Leukemia has been retconned then it is within her established character traits that she would travel south of the border with her son John Connor when Skynet launches its initial attack against mankind (AKA Judgment Day). With Skynet's military background it would likely be able to pre-empt any counterattacks from surviving US military forces but would be less effective against an unpredictable, unorthodox, guerilla resistance force. As such, the recent castings would seem to suggest that the new Terminator movies script, which is being written by Bill Ray under James Cameron's watchful eye, will likely be set during the early years of the Future War, with the Connors establishing a resistance in South America while the remaining US military Forces are dominated by Skynet's superiority. Luna's casting, in particular, would also suggest that Skynet is aware of the Connors efforts and sends one of its Infiltrator Terminators to terminate them. By the conclusion of the movie, we expect Sarah Connor will have sacrificed herself to save her son, allowing a new cast to complete the franchise in a new trilogy should the first movie be well received by fans, critics, and the general audiences.
We also expect Arnold's role as the Terminator will also come to an end by the conclusion of the movie. However, how his role initially impacts the movie and how the movie's narrative will rewrite the last three Terminator movies out of canonicity remains to be seen. What also remains to be seen is who will be cast as John Connor, although Reyes casting in a prominent role would seem to suggest that should John Connor feature in the movie, it will likely be in a small capacity. All together this paints a picture that the majority of the movie, if not is entirety will be visually reminiscent of 2008's Terminator Salvation, although directed by Deadpool's Tim Miller and overseen by the franchises creator Cameron.
As for MacKenzie Davis' role, we have no idea whether she will be part of the South American or the North American resistance, but we suspect she will portray a resistance fighter in some capacity.
