Watching an amazing (or amazingly terrible) movie with friends is a fun pastime in and of itself, but add in a drinking game to the mix, and you've got yourself a hilarious pop culture party in full swing. The rules are fairly simple for cinematic soirées (drink whenever 'this' or 'that' happens on screen), but they naturally vary with each round, depending on which movie you've decided to whack on the telly. Have a swig every time a zombie bites it in Zombieland. Take a tipple every time someone says, "Mr President" in Independence Day, but avoid having a drink every time Bella sighs, "Edward" in the Twilight movies - not because your liver will revolt, but because that would mean having to watch the Twilight films. Don't worry, you won't find that latter example here, because only the very best movie drinking games have made it onto our list below.
25. Anchorman (2004)
The movie: Will Ferrell stars as the mustachioed broadcaster living it up as the network's main attraction, only to get shafted when he's lumbered with a female co-host in the form of Christina Applegate's Veronica Corningstone.
Take a drink when: Ron addresses San Diego or makes a bizarre exclamation (i.e. "By the beard of Zeus!"). Brick Tamland says something stupid. An Apatow favourite makes a cameo.
24. Zombieland (2009)
The movie: This horror comedy takes place in a post-apocalyptic world - it's there in the title, isn't it? The nifty part is that the undead have been roaming for a while when we meet Jesse Eisenberg's survivor, who tells us - via amusing onscreen captions - of certain rules he has to stay alive.
Take a drink when: A rule comes up on screen. Somebody uses a place as a character name. Twinkies are talked about. Tallahassee kills a zombie.
23. Top Gun (1986)
The movie: '80s action classic starring Tom Cruise as a rebellious fighter pilot, Maverick, who goes up against the oppression of... err... those who don't like really really fast planes? There's shirtless volleyball too.
Take a drink when: There's a homoerotic look shared between characters. Characters high five. Maverick goes against the rules. The song 'Danger Zone' plays.
22. Scream (1996)
The movie: The best slasher flick of the '90s, starring Neve Campbell as the target of a movie-loving psychopath. Both witty and scary, it launched the careers of its young cast and schooled a generation on horror movie trivia.
Take a drink when: Someone references another horror movie. A phone rings. Gale Weathers makes a bitchy remark to her cameraman. Ghostface appears.
21. The Hangover (2009)
The movie: A group of pals on a ker-azy stag party (Bradley Cooper, Zach Galifianakis, Ed Helms) wake up in Vegas the next morning, but can't remember anything about the previous night. They probably played too many movie drinking games.
Take a drink when: Stu touches his missing tooth or mentions it. Someone says remember. You see a Vegas landmark. Alan copies Phil.
20. Zoolander (2001)
The movie: Ben Stiller stars as quite possibly the stupidest man alive, Derek Zoolander. A model with looks that could kill, he becomes embroiled in a bizarre plot where only models can save the world.
Take a drink when: Zoolander does the face. There's a celebrity cameo. Will Ferrell looks like his dog. Somebody says 'Blue Steel'.
19. A Nightmare on Elm Street (1984)
The movie: Freddy Krueger haunts the dreams of the Elm Street children, whose parents fried him to death when they were youngsters. The plot unravels through the experiences of Nancy, a teenager and Freddy's main target. He'll do anything to get her - even turn himself into a... err... phone handset.
Take a drink when: You're not sure if somebody is awake or dreaming. Freddy Krueger's on screen. You see Nancy's house from the outside. Horror legend John Saxon appears.
18. The Wolf of Wall Street (2013)
The movie: In his most recent collaboration with Martin Scorsese (ignoring that weird casino commercial), DiCaprio plays real-life stock market sleaze Jordan Belfort - a man who will stoop low to go high. By that I mean, get high.
Take a drink when: Someone says fuck. Anyone snorts anything. Something ridiculously decadent and hedonistic happens.
17. Gremlins (1984)
The movie: A small American town is overrun with horrible little beasties who turn Christmas into a nightmare, particularly for Zach Galligan's teenager.
Take a drink when: A gremlin is killed. Gizmo does something cute. Gizmo gets tortured. The gremlins do something crazy.
16. Die Hard (1988)
The movie: Coolest action movie ever made? Probably. Bruce Willis stars as a cop who's trapped in a building with 12 terrorists at Christmas time. He's the only thing stopping them from delivering more than presents...
Take a drink when: Anyone uses a radio or walkie-talkie to communicate. McClane kills a bad guy. There's a Christmas reference. McClane talks to himself.
