I have to disagree with a lot of the comments here. Although it has been long proven that a film version paradoxically actually boots ticket sales (see Chicago, Phantom), having a Hamilton-style pro shot film of the stage show is, in my opinion, a bad idea if you want to get people to come live. Personally, as much as I love live theater, I'm not going to pay $140 a ticket to see the tour of Come From Away if I can watch a pro shot of the stage show on my 70" television at home.
At the same time, I can't help but feel that the producers of Come From Away are filming it because they know many audience members won't see it live. Unlike Hamilton or Dear Evan Hansen, which cater to younger audiences, Come From Away's key demographic is your standard 45-plus, upper middle class audience. A lot of people in that demographic - specifically people age 60 or older and other high risk COVID groups - may choose to never go to the theater again or will only go if it is something they really want to see.
That said, I think that all theater is going to start to have live-streamed performances in the future. It will be like sports, in that of course it's more enjoyable to actually go to the game, but if one can't, watching it on TV is the next best thing. I'm talking two to three cameras, low cost filming. However if it's a six to eight camera, multi-million dollar endeavor like the Hamilton film was, to me that would signal the end of a show's run. It's like, "You didn't get to see it? Well, we're closing soon so here's what you missed." Hamilton might be the kind of show that is an exception however since it is so extremely popular and loved that people may go just to see a new cast interpret the material, and to have the the communal experience of seeing it live.
