John Cho isn't sure that the 'whole' cast will return for Star Trek 4
John Cho, who plays Hikaru Sulu in the previous two Star Trek movies, said he felt getting the full cast for Star Trek back for a fourth film might be difficult, considering they all originally signed three picture deals:
"The reason I hesitate is just wondering if we could get everyone. It seems to be an all or nothing proposition. I want to say, for me, sure, let’s do another. I enjoy that group. I enjoy what Star Trek films do in general and say in general. And I will say one of the pleasures of having been in Star Trek movies has been seeing what effect they have in society, like astronauts saying, “I kind of got into this line of work because my imagination was sparked from watching ‘Star Trek.’” That is very cool. What I’m trying to say is, I just stand by that product. Getting a whole cast together, that’s tough."
