The 2 1/2-minute clip also finds "Game of Thrones" star Emilia Clarke portraying a young Sarah Connor and Arnold Schwarzenegger reprising his role as the Terminator.

"Genisys" finds John Connor worrying about a future attack when TECOM spies reveal a new plot by SkyNet to strike from both past and future.

The new trailer follows the release of a motion poster where a skeleton-like robot head with red eyes appears to be deteriorating.

"Terminator: Genisys" was directed by Alan Taylor ("Thor: The Dark World") and will be released in theaters July 1.
