IMDbPro lists that filming began in February of this year. Not that five or six months wouldn't be a long shoot, but I seem to remember that some scenes were shot as early as last fall. Unfortunately I've seen no glimpse of Meryl on set or in costume. My guess is that we'll have to wait for some production stills or a teaser. Considering the film won't be released for another 18 months, those glimpses might be a while. Director Rob Marshall should have plenty of time for post-production.
