I posted this in the other thread, but I'll clarify here…
There's absolutely no reason that a new cast wouldn't work, provided it was carefully selected on the basis of cast interaction, not just salary/visibility. Use some up-and-comers….s'why I mentioned Reynolds and Black. In fact, a new cast could add a lot to the franchise, again, if it was carefully constructed. Breathe a little life into her, as it were.
I mean, think outside the damn box a little.
Imagine Danny's old script w/ some good cast interaction, some cool, old-skool humor, and no tackiness.
Don't get me wrong, I'd LOVE to see a few of the old guys back…..but not as primary cast members. Honestly, they're too damn old.
Have you seen Harold Ramis lately?
Bring Danny, Ramis, and Hudson back as the head honchos, but I just don't think it could go any farther than that.
Yes, it's a matter of character interaction…..but to think that only the original cast has this “edge,” well, that's just short-sighted. There's a number of great combinations that could work wonders in a new GB film, even if the formula was tweaked a bit (while still retaining similar character archetypes and interaction style).
Believe me, average Joe/Jane won't actively say “that's the Egon character;” look at the movie from a standpoint outside the realm of the Ghosthead. A new cast most certainly would work….it's not just the premise of the movie, but also the interaction style, which isn't exclusive to those actors. The point of making new characters with similar personality types is to “tweak” the old characters a bit, give them a contemporary edge, and maintain that “old-skool,” average-guy-style comedy that made the first two films work so well. A large part of those movies worked because hey, they weren't futuristic scientific technofiles. they were regular guys in an extraordinary position.
Yes, the character archetypes would be roughly extended to a third film….but hey, that happens in ALL movies. It's unavoidable. But the new movie will retain new people, and that will certainly breathe new life into the crew.
