Dinner for Schmucks, the 2010 American version
Tim (Paul Rudd) is a financial analyst trying to earn a promotion to account manager at a well-to-do Wall Street financial firm. After impressing his boss he is invited to a monthly dinnerparty, where each invitee will bring one idiot, so all the Wall Street bros can surreptitiously mock them, with the guy who brings the biggest idiot being crowned the winner. Enter Barry (Steve Carrell), an amateur taxidermist, IRS drone and complete moron.
To put it bluntly: Barry, through sheer stupidity, completely ruins Tim's life. And Tim, played by charming, loveable Paul Rudd, is not nearly enough of a piece of shit to deserve that. DfS is based off a French film, Le Diner de Cons, and in that film (or based what I read on the WIkipedia article), the commensurate Tim, Pierre, is a tax cheating philanderer who regularly attends these dinners not because he's desperate to get ahead, but because he's a pos who enjoys humiliating his supposed lessers. These are smoothed out in the American remake because why? I don't know. It just makes this movie a cringefest as Barry ruins this handsome everyman's life. In the original I imagine part of the point is a cheating businessman's hubris in thinking it was a good idea to try and humiliate a member of the government bureau that polices men like him. Pierre has lost sight that the fool is both a tornado of destruction who brings nothing but ruin, but also someone who holds real, legitimate power over him: in the American remake this is invested in Zach Galifanakis' character (the best part of the movie) and its payoff is him shouting that he'll audit everyone as he leaves the eponymous dinner- and the movie altogether- embarrassed. The irony that Wall Street financial execs have made an enemy of a vindictive IRS drone is instead "and then their house burned down."
Anyway the movie is painfully unfunny and possibly a remnant of a time when all you had to do to get an audience to hate someone was to show they were a competent Wall Street bro, the film came out in 2010 after all. Unfunny and cringe. Do not recommend.
