I can agree with a few on here but I'll add a new one.
SAHARA
It was just good enough with room to grow the characters and the exploits should one have happened.
A very fun movie with lots more Clive Cussler novels that could be adapted. Unfortunately, I suspect that Cussler's lawsuit against Paramount has soured its chances.
Count me among the folks here who think
Gremlins 2 is better than the 1st one. Occasionally, there are sequels that are simply better because they have learned from & improved upon the original.
Addams Family Values is the other sequel I would put into this category, and maybe
Shanghai Knights.
I would have liked to see David Lynch (or at least his cast) do some
Dune sequels.
While I think its time has passed,
Ghostbusters 3 would have been awesome had it come out in the early 1990s.
I'd love to see Bryan Singer & Brandon Routh get the chance to do a follow up to
Superman Returns.
They say they're working on another
Riddick movie. I hope so but I won't believe it until I see the trailer. Same with
Underworld IV.
Whatever happened to
Dusk Watch, the 3rd movie in Timur Bekmambetov's
Night Watch series?
I think I've got a pretty good idea for
Galaxy Quest II. The 1st movie ended with the old cast returning for a new version of the TV show. As the sequel begins, a brash, dim-witted actor/producer (think Kevin Sorbo on
Andromeda) takes over the series and writes out most of the original cast in favor of younger, "hipper" actors. This then causes a violent youth revolt on the alien planet where they think that the show is a documentary. Both the old & new casts are drafted to lead their respective sides in the civil war.
