The identity of Matt Smith‘s character in ‘Terminator: Genisys‘ has been shrouded in secrecy from the moment it was announced that the former ‘Doctor Who’ star had been cast. But it seems that shroud may have at last been pierced.

Based upon anonymous reports from a test screening in Arizona, Latino-Review is claiming to have uncovered the identity of this mysterious figure. Although this information is unconfirmed, it goes without saying that if it’s true, it would constitute a potentially major spoiler. Consider yourself warned.

Latino-Review reports:

In ‘Terminator: Genisys’ Matt Smith plays the embodiment of Skynet. Similar to Helena Bonham Carter’s role in McG’s ‘Terminator: Salvation,’ Smith will be the antagonist system given form, different from the nebulous corporate villainy of ‘Terminator 2: Judgment Day’ and the vague apocalypse technophobia of the first.

Well, there you have it. If this is true, it’s certainly unexpected (though not impossible). What little publicity there has been around Smith’s character has seemed to depict him, if only by implication, as human, presumably a member of the Resistance. This, however, could just as easily be a red herring. Or Smith could spend the bulk of the film alongside John Connor only to be revealed as a machine late in the game.

The underlying concept also would not be entirely unprecedented in the Terminator mythology. With regard to ‘Terminator: Salvation’ alone, the notion invites comparisons not only to Helena Bonham Carter’s character, but also Sam Worthington’s, who was ultimately revealed as a Terminator who thought he was human. Similarly, ‘Terminator: The Sarah Connor Chronicles’ also dealt with the idea of Terminators infiltrating the resistance and even attempting to alter history by impersonating specific individuals.

In addition to Matt Smith, ‘Terminator: Genisys’ sees the return of Arnold Schwarzeneggar as the T-800 alongside Emilia Clarke as Sarah Connor, Jai Courtney as Kyle Reese and Jason Clarke as John Connor. The film will be in theaters on July 1st.
