Best movie duology?

Yojimbo and Sanjuro

Guns of Navarone and Force 10 from Navarone

The only real connection imho is the title, but I like them both.

My personal favorite is Weekend at Bernie’s and Weekend at Bernie’s II.

My thoughts exactly. Two very good films that, together, make a great one.

There’s also the case of Cat People and Curse of the Cat People, both produced by Val Lewton. Cat People is a masterpiece of subtle horror. Curse follows the characters and actors from the first film, it’s very different in tone, dealing with loneliness and just a touch of the supernatural (or was it?). They are two very different films, but the studio insisted that Curse be linked.

The creative team behind Airplane! (Jerry and David Zucker and Jim Abrahams) weren’t involved in the sequel, and it showed. So, IMO, it fits the OP’s bill, but the second one should never have been made, and the original creative team never saw it as a potential duology.

In early '84, when I was a student at UW-Madison, the three of them put on a screening of a rough cut of their new film (Top Secret!), which I attended. Afterwards, they had a Q&A session, and they talked about what happened with Airplane and Airplane II, which went something like this:

Paramount: Hey, Airplane was great! It made a fortune! We want you to make a sequel.
ZAZ: We’ve already done all of the good disaster movie jokes. We want to do something else.
Paramount: No, no, no, do another Airplane movie!
ZAZ: We don’t want to. It’ll suck.
Paramount: Well, see, we own the Airplane rights, so we’re going to make a sequel. You can be involved, or not, but it’s going to be made anyway.
ZAZ: Knock yourselves out.

And a great example of how to make a sequel without just re-doing the original. The second one was fresh and even kind of made fun of itself.

Thanks.

Yeah, but that was one over-long movie that he split later. Great, but really plays as one movie(and filmed as one movie).

I know some people love the Conan movies with Arnold, though I greatly preferred the first one over the second one. I also really liked Hellboy and Hellboy 2, with Hellboy 2 being the superior one.

Some people think Jewel of the Nile is a bad movie, but I liked it enough to consider it and Romancing the Stone a nice duology.

Both Addams Family movies are really good, too, with the sequel being the better.

History of the World : Part one
and
History of the World: Part two

This was my thought, too. While the sequel isn’t up to the excellence of the original–few films are!–I like it a lot, especially Terry the Toad’s story arc.

There was actually a third in the series, Addams Family Reunion, with some of the cast members from the previous two (Carel Struycken and some minor others), but it was a TV movie so we can pretend it never happened.

This would be my winner.

Clerks and Clerks II, although not the best, should be in the conversation.

It should, they’re quite good, but there’s a Clerks 3 in the pipeline.

I’m going to go with one that’s not on the wikipedia list:

Snake Plissken’s Escape movies!

Escape From New York
Escape From L.A.

Not the greatest cinema epics ever produced, true, but I love them both.

True, true. I wasn’t counting it. The vast majority of cast was not in it and the behind the scenes people were different.

This reminded me–The Mask of Zorro and The Legend of Zorro, with Antonio Banderas and Catherine Zeta Jones are both pretty good. The second is inferior to the first, but it’s still fun.

Boondock Saints and Boondock Saints 2: All Saints Day
Both fine movies with the edge going to the first.

Which is weird (although I’m sure it’s true) because they feel like completely different movies. Part 1 feels like an hommage to Hong Kong kung fu flicks, and Part 2 to spaghetti westerns.

I much prefer Part 1.

No one (unless I missed it) mentioned Ghostbusters yet? I know some people have an irrational dislike for 2, and it’s definitely not as good as 1, but they’re still both great. Certainly better than the upcoming piece of shit redo will be.

I thought WAB 2 ruined some of the things that made 1 great. I mean, did we really need all that voodoo nonsense? 1’s a true 80’s classic, 2 is just dumb.

Ghostbusters definitely a good one. Both movies instantly stop the remote control for me.

Fantasia and Fantasia 2000.
