I've noticed some interesting things from the trailers on the official Youtube channel:-
The Russian teaser, for СПЕКТР, starts with "для зрителей старше 16 лет" which translates to "for viewers over 16 years" - The teaser also reveals the Russians/русские люди will be getting the film in October.
What, if anything, is unsuitable for Russian under-17s to watch?!
As I pointed out in the UK release dates thread, the trailers have also given some idea of release dates for other markets:-
