The Hangover ripoff?
Was this script in the works around the same time as the hangover was being released? It just seems that it has the same post-stag party bafoonery as we see in both the Hangover movies. Both movies have the anal retentive, the playboy and the disturbed (by break up or mental problems). Very similiar, just with accents.
Dont get me wrong, i liked the Hangover franchise and found this movie very funny as well. I guess movie history is full of stag and wedding humour, and its just the timing that makes it look like a rip off.
