How many people were on this ship?
Considering that a good bulk were in the ballroom... and maybe a few in their cabins. Count in the five people working in the kitchen and three people on deck, all in all, there must have been about 200 people in total on a cruise liner that would cater to thousands of guests?
I can't believe they blew the lousy CGI budget on shots of fake bubbles coming out of the capsized cruiser, but couldn't spend anything on phoney shots of lots of people (you know where they get a group of people and multiply the same shot to look like there's a huge crowd?). At least they could have tried.
