I posted this on another thread related to a Twister sequel, but I will repeat it here. If they want to get the tornadoes right they need to take a look at Leigh Orf's computer simulations and study close up high def videos of tornadoes. The movie "13 Minutes" right now has the most realistic CGI tornado/supercell to ever hit the big screen, but they kept it pretty simple, which worked well for that movie. "Twisters" will require a lot more action.
The CGI in the movie "Into the Storm" felt like a more refined version of the CGI tornadoes in the original Twister movie. While they were better, they still failed to look truly realistic. The real problem with "Into the Storm" was a dull plot and characters that were forgettable.
I am very curious to see how Bill and Dusty are written out of the sequel. Their absence will no doubt be glaring. It presents filmmakers with quite the challenge of connecting the sequel to the original. Typically this doesn't work very well, however if done right (Top Gun: Maverick) the results can be a sequel that not only lives up to expectations, but rivals the original. For "Twisters" to recapture the magic of the 1996 original, filmmakers have to be as true to the original as possible. They MUST get Hellen Hunt on board. Recasting Jo Harding will doom this movie. They need to bring back the original chase team and have a scene where Jo visits Aunt Meg in Wakita.
I am curious to see how they score this film. Mark Mancina scored the soundtrack for first film and did a marvelous job combining a touch of Americana with a catchy eerie undertone. Van Halen tied it all together with "Human's Being" and "Respect the Wind". Do they bring Mancina back to reprise the original score, or do they go in a different direction? I have seen some chasers suggest Hans Zimmer, and while his work is iconic and among the very best, I am not sure if his "style" fits Twister. I may be wrong on this, but he wouldn't be my go-to. Honestly, I like a darker undertone and would like to see someone like an Atticus Ross do the original score.
