Casablanca and Grim Fandango
The similarities between the two are AMAZING.
Alot of characters from Grim in year two such as Chowchilla Charlie, the roulette keeper, the chief of police, etc. are inspired from characters in Casablanca.
The story is similar and Manny wears the exact same suit as Rick in Casablanca...
I can't even tell you how much the two resemble eachother. Just go see Casablanca!
