Paramount Confirms Chris Hemsworth Will Return in Star Trek 4.
Hemsworth's character, George Kirk appeared briefly -though memorably - in the 2009 Star Trek reboot which is now known as the Kelvin timeline. At this point is far too early to speculate how or in what sense will George Kirk cross paths with his son, James Kirk (Chris Pine).
For this next Star Trek film, J.D. Payne and Patrick McKay will write the script. The two were the first writers on Beyond when Robert Orci was going to direct. J.J. Abrams and Lindsey Weber will produce this next Star trek movie via Bad Robot Productions.
