That’s the same thing I was thinking- even though it comes from a book, it was made into a movie. I believe Douglas Adams said drinking it is like being hit in the head with a lemon wrapped inside a brick.
From our own Straight dope
Ian Fleming gives a recipe for his Bond’s preferred libation in the first Bond book, Casino Royale (1953), chapter 7:
“A dry martini,” he said. “One. In a deep champagne goblet.”
“Oui, monsieur.”
“Just a moment. Three measures of Gordon’s, one of vodka, half a measure of Kina Lillet. Shake it very well until it’s ice-cold, then add a large thin slice of lemon-peel. Got it?”
I’ve always wanted a Tahitian Lady – flaming.
In Cannery Row, Doc went into a diner and ordered a beer malted.
After reading that book I did actually try a beer milkshake. I thought it might not be too terrible if made with homebrewed stout. I was so wrong.
Lots of drinkies in [url=http://en.wikipedia.org/wiki/Withnail_and_I#Drinking_Game]Withnail And I". 
Oh yeah, and lousy coding even without any drinks. 
Oops.
I used to work in a cuban resturaunt (Cabana in the south street seaport)
And there we didn’t use grainualed sugar, but simple syrup. Makes a better mojito imho. See having a liquid to bruse the mint into helps release the flavor.
For a mix up try a mojita, same deal just add a half oz of grenidine.-
Not exactly from a movie, but:
On an episode of The Simpsons, homer and moe invent a drink called the flaming homer. We used to have these in college:
2 shots rum, non-spiced
3 shots gin
3 shots vodka
2 shots whiskey
2 shots tequila
1 shot blue curacao (sp?)
top with grain alcohol or 151 (here in Michigan everclear isn’t sold)
light on fire
blow out, and enjoy 
You only need one.
What about the cough syrup?
That’s what the blue curacao was for I suppose. Hey, I didn’t invent it. Actually, after having one, you are kinda sad that it was invented at all
