Was the city all cgi or is it actually Hong Kong?
shareI would guess CGI.
shareIt looks pretty modern and spectacular, so either cgi or one of the bigger cities like Hong Kong, Shanghai, Tokyo, maybe Singapur?
shareI'm sure it was CGI. Besides the fact no real city looks like that, I don't see them flying around the world to film scenes on-location for every single scene the way you would be more likely to in a movie.
That being said, it looked very realistic and I'd love to see more there.
