As a huge fan of Dante's work, I think it is a tragedy how little movies he's been able to put out, especially recently. Still, I was a huge doubter of Small Soldiers, maybe because of how dumb it looked filtered through the Burger King ads, and didn't even finally see the movie until about two years ago. Of course, I loved it, and I regretted not seeing it in the theater. But now my low expectations extend to the sequel, because if Dante isn't allowed to do it, the result will probably be as dumb as I had thought the original was going to be. I am already a bit worried about the unproven screenwriting duo, though I have to remember that Gremlins 2 had a different writer than Gremlins and it worked out brilliantly.
Others that I'd want to return for the sequel are Jay Mohr and David Cross and all the actors who provided their voices for The Commando Elite (hurry, some of the Dirty Dozen guys are getting up there) and The Gorgonites. The rest of the cast, especially Kirsten Dunst, are not required. Dante is supposedly currently working on The Man With Kaleidoscope Eyes, a film about his old boss, Roger Corman, and the making of the 1967 film The Trip. But since he isn't going to be involved with Gremlins 3 (such a shame, if it happens that way), he can follow up Kaleidoscope with Small Soldiers 2.
