Happy 30th birthday Ghostbusters! Fellow ghostheads, I bring to you some previously unseen pre-production images used as inspiration for the gadgetry that wound up in both Ghostbusters and GBII. I also have shared a whole slew of pre-production Ectomobile pictures you can check here! So, without further adieu, here are the images!
Slime scooper!
Ecto-goggles
Proton pack inspiration?
Looks like we’ve been misnaming it the whole time, it’s a slime slinger
The photos of the Flame Thrower are obviously inspiration for the tanks of the Slime Blower. 
Cool, loving the behind-the-scenes look.
These are really amazing!
Thank you for sharing them! I always appreciate a good behind the scenes glimpse of things
Slime slinger Ben 
Awesome photos!
Interesting how similar the “holographic goggles” are to the ecto-helmet devices seen in the RGB episode “Cry Uncle.” I wonder if that’s just a coincidence, or if one was inspired by the other…..
Pretty awesome pictures
