Hi all, im looking a for a movie a watched long time ago, probably between 2000-2012. I was certain main actor was RDJ but i looked for it in several searches and found nothing. Movie was a drama staged in 1950s and plot was about a deformed man (something like a lion or cat alike) that finds a group of people where he shares his weirdness and feels comfortable with, in this group was a super tall or skinny guy, i think siamese brothers and a girl who he starts a relationship with, its all kinda blurry and some details might not be accurate, i do remember it was a little disgusting, or had some scenes very grotesque, sex related or explicit. I hope someone can make smothing out of this info. Thanks a lot.
