How to Murder Your Wife (1965)
You’re at a party. A blonde bombshell steps out of a cake. You wake up in bed with her. And married to her. What do you do? If you answered, “What would Jack Lemmon do?” this film might supply the answer. Even if it doesn’t, it’s worth watching for some superior (if dated) comic performances.
The Hangover (2009)
Vegas was created to feed partygoers everything they could want until all they want is darkness and sleep. The Hangover took that to another level with hilarious consequences – as expected from a cast containing Zach Galifianakis and Ken Jeong. Mike Tyson makes a cameo (as you'll know from our list of the best movie cameos ever).
200 Cigarettes (1999)
It’s New Year’s Eve and a group of young party animals are dealing with their relationships, loneliness and individual mental-problems – making for a film that leaves you feeling emotionally hungover (a little like you’ve smoked the titular quantity of Bensons). The stunning cast comprises a pair of young Afflecks, Kate Hudson, Dave Chapelle, Paul Rudd and Elvis Costello.
Weird Science (1995)
Two geeky teens use the weird and wonderful world of computers to create their own perfect woman. Inevitably, lightning strikes and the superbabe, played by Kelly LeBrock, magically materialises. Funnily enough, their popularity picks up immediately. No wonder mail order brides took off.
No LA party is enough for Jon Favreau and Vince Vaughan’s characters – so they head to Vegas. Snappy dialogue, great ad lib acting and some serious screen chemistry made this joke-dense jape a jump-off-point for both these actors’ comedy careers.
