Hmm I'm not sure about the others but the link doesn't work for me.
Have they resolved the squabbling? Some time back I've heard that part of the main cast didn't want to do another movie.
If you copy the link, paste it and edit it. you'll be able to clear out the junk and get it to work. Also I can't blame Pine or Hemsworth in the slightest. As I understand it, what happened was that Hemsworth and Pine originally agreed to come on board for a specific amount of money. Then after Star Trek Beyond, the budget got slashed for the 4th film and as I understand it, they were both told they were getting a fraction of what they were originally offered. No one likes a bait and switch - especially when it comes to a job.
