At one point, Chris Hemsworth (George Kirk) was certain that he would be returning for the next Star Trek movie, but that is no longer the case.
Originally, Hemsworth said that there had been “a way of reinserting [George Kirk] into the world. I … always thought, maybe, there was a possibility of him coming back in some way. I didn’t know how or what, but [J.J. Abrams] was pretty enthusiastic about what they had planned.”
But now, with Quentin Tarantino coming forward with his own pitch for the movie, Hemsworth does not know if he will be part of Star Trek 4. “I don’t know,” he said, when asked if he would be in the movie. “It’s a reminder to call J.J. and ask the same question because I haven’t heard any updates on it either.”
