The Hollywood Reporter estimates that raises added an additional $10 to $15 million to the film's budget. The news comes just as Quinto and Zoe Saldana recently posted images of them going to costume fittings and what may be the beginning of principle photography based on some reports. However Star Trek 3 producer David Ellison spoke with Collider and said "we start shooting in 10 days and we're shooting in Vancouver and Dubai." More likely set and costume prep has begun in Vancouver as it seems unlikely filming would begin now to just have to close up shop for the Fourth of July weekend so the week of July 6th start date is more credible.
I have to admit I am very surprised by Chris Pine signing on to another movie as he and Zoe Saldana just seemed to really begrudge being part of Star Trek. It always felt like they were going through the motions, faking their interest but really only interested in the higher profile it brought them and it was just a matter of the order they bolted once their 3 film contract ended. Of course part of Pine's re-up could be because his other movie attempts have all fallen way short of expectations as the two Star Trek films are his most successful films to date. Meanwhile Saldana has Guardians of the Galaxy, Avatar 2 and 3 on the horizon. The article doesn't mention the state of her Trek 3 pay or a potential Trek 4 contract so I think its safe to assume she still has at least one foot out the door. Let's put it this way, if rumors start of a character death, I am just going to assume its hers (and nope no such rumor current exists and I am not trying to start one). Star Trek Beyond is set for release on July 8, 2016.
