J.K. Simmons talks Terminator Genisys sequels

J.K. Simmons has confirmed future Terminator Genisys follow-ups have already been written.

J.K. Simmons has confirmed he is fully signed on to star in Terminator Genisys sequels.

The 60-year-old actor portrays Detective O’Brien in the new sci-fi feature, which is based on the original 1984 picture about a lethal cyborg from the future.

The fate of J.K.’s persona O’Brien appears questionable in Genisys, but the actor confirms the character is likely to appear in future Terminator films.

“I am signed on, so if there are sequels I will by God be there,” he told SlashFilm.

“There are a lot of ways we could go with O’Brien and we’ve actually have had those discussions already, so I do know where it goes — but that’s part of the fun of the character, he’s the only guy in 2017, in the regular world, that has a clue what’s going on.

"Nobody believes him, but he does sorta know what’s up, or is beginning to figure out what the whole story is here.

"So I think if we make the sequels as they continue, I think O’Brien’s credibility level will develop.”

J.K. says follow-ups are dependent on how well Terminator Genisys, which was released to American theatres on July 1, does at the box office.

However, the star noted scripts have been written and planning has already been done for two sequels.

But the movies are currently awaiting a green light from studios.

Early box office calculations see Genisys earning around $45 million in its opening weekend - $10 million less than anticipated.

The Paramount Pictures production, which also stars Emilia Clarke, Jai Courtney and Arnold Schwarzenegger, was created with a budget of $155 million.
