Here's the amazing thing about this trailer: I know it's the latter, but everything about it looks like the former. Yes, this is a SFW YouTube trailer for an adult film called Bridesmaids. But the amazing thing about it is how cleverly disgused it is as a rom-com. I'm seriously impressed by the production quality. They've managed to get the screwball wedding movie trailer recipe down pat. It's by Digital Playground and stars Jesse Jane, Kayden Kross, and Stoya. The man of many-a movie, James Deen, makes an appearence as well.
Spoiler alert: All the Bridesmaids end up in jail. BUT HOW?!?!?!?! Definitely involves some sort of kinky incident with male stripper cops. I haven't seen it yet, but chances the final wedding scene ends with the bride and groom cutting the cake and then having a gangbang with their bridal party are pretty damn high.
