Why would her boys being at school be a problem? She did Streetcar for 3 months last year, and it wasn’t during the summer. She’s used to work abroad and not only in August!
They could film this fall, why not. The only issue I can see is that if they start in October for example, and if they’d agreed to do 8 or 10, it’ll be extended during winter and I can see Gillian and David refuse to film in Vancouver during winter. (I would totally refuse! lol) IWTB seemed to be a pain in the ass to film! So maybe they’ll film in LA this time…
