A TV production schedule and a film production schedule are very different things. Which is why TV shows don’t have the same quality as movies. So it’s really hard to compare the two & guess how much or little the guys will appear.
As we all probably know, every film is different, every director is different, every set is different. We know that the OGB’s filmed for at least a week so it’s impossible to know how much or little they’ll be in the film. For some movies it takes 7 days just to shoot a single scene, depending on the technical requirements and the overall complexity.
Jason Reitman has a reputation for an being an extremity fast shooter. I think I read somewhere he can do somewhere around 15 set ups per day. But this is also his first BIG film. Visual effects, and especially practical effects take a looong time to set up. This film also seems to be more visual than his others. That all takes alot of time to set up.
Ghostbusters 1 & 2 have a very dry style, not a lot of fancy camera moves & I think Jason will stick to that. Since he’s not an action director they probably shot a lot of the action scenes on 2Nd unit. All that lends itself to the notion that he can probably film quite a bit in 7 days.
The movie shot for just over 60 days, right? 65? Something like that. A week might also mean a business week so we could be looking at between 5-7 days on a 60ish day shoot. It’s a small enough number that it still concerns me greatly that the OGB’s are being shoehorned into this movie just so we can see them suit up again. I’d die happy seeing them in GB gear again, but I don’t want it to come at the expense of the movie itself.
