It really wouldn't even take much CGI; you just do a clean plate for every shot and then a shot with the actors, and composite them at say 90 percent opacity, just transparent enough to convey the desired effect. The only really complicated shots would be the ones where the present selves have to interact with the ghosts of their past selves.There are a lot of grand old theaters that have been abandoned for decades that would provide a great atmospheric setting for the soon-to-be-demolished Weismann Theatre. The production crew could fix it up just enough to be safe for the actors, film all of the present day stuff, and then fix it up properly for the rest of the film when the characters see the theater in its prime.As a side benefit, some community would have a piece of its cultural heritage restored to it.
