Let's try to leave direct sequels out of this, unless they are really personal.

I sometimes break out my Universal Monsters dvds at Halloween and watch something like The Mummy or Creature From the Black Lagoon. I also like to watch the movies Robocop and Starship Troopers together. Mainly because they were done by the same writer,producer, director team. Also, the world portrayed in Robocop could easily be the same one in Starship, except in the past.

Other picks:

Prometheus and Alien-not direct!

Scott Pilgrim and Ghostbusters

When I watch more than one movie at a time I usually like to choose two different genres to break up the mood a bit but occasionally I will do a "double feature". My last few double features have been:

E.T.: The Extra Terrestrial
Close Encounters of the Third Kind

Gladiator
Kingdom of Heaven: DC

Robocop
Dredd

I think Jackie Brown and Out of Sight might make a good one, with the crime theme and Michael Keaton's character connecting them. Provided the combined length of about 4.5 hours isn't a problem.

Ghostbusters & Frighteners

Jaws & Jurassic Park

Shawshank Redemption & Green Mile

Almost Famous & Fast Times At Ridgemomt High.

Grindhouse and Hobo with a Shotgun

Or

Machete and Hobo with a Shotgun

American Graffiti

with

Dazed and Confused

(if I could find a flick set in the eighties that featured a lot of driving and music, then it'd be a sweet trilogy)

The Warriors with The Wanderers and/or The Outsiders.

Two Depp movies...

Sleepy Hollow + From Hell

Robocop + Starship Troopers

Shane + Mad Max 2

Chinatown + LA Confidential (+ The Big Lebowski)

Sound of Music
Planet Terror

Fail-Safe + Dr. Strangelove

Romancing The Stone + War of the Roses

Back To The Future + Peggy Sue Got Married

GoodFellas + Casino

I think this would be an interesting double feature...

The Innocents
+
The Others

The Innocents
+
The Nightcomers

I actually like:

From Hell

&

The Raven


The themes are so close.
