While I think it will have it's biggest drop to date against HG i won't drop massively as I think they have different audiences and James Bond is way more popular then HG there is no competition.
Don't think that is the aim they should be delighted with 85 million ish and 3rd all time is still an amazing run as good as expected after Skyfall's record breaking run.
Always would be in the UK James bond is critic proof will make money even if it was truly horrendous also UK reviewers always look favourably on it so get's better review's here then anywhere else.
Look's to be huge Universal have marketed this very well and is a lot of hype about this film. Will be big OS $500 mil minimum thanks to China i'd go for $550 mil OS.
