“Mother Schmuckers” is the feature debut of brothers Harpo and Lenny Guit, who wrote and directed the film. Here’s the synopsis from the Sundance Film Festival: The festival synopsis comes with a caveat: “Not suitable for audiences under 18.” The cast of the movie includes French favorite Mathieu Amalric (who’s also starring in Wes Anderson’s upcoming “The French Dispatch” later this year), plus some fresh faces including Maxi Delmelle, writer/director Harpo Guit, and Claire Bodson (who stars in “Young Ahmed”). Filthy and yet oh-so-charming, the Belgian filmmaking duo of Harpo and Lenny Guit (who will likely never be confused with the other Belgian directing duo, the Dardenne brothers) are quite the Midnight discovery. Their madcap adventure goes gross “Three Stooges.” It’s sparkling with energy, lo-fi visual trickery, and the ingenuity to make every creative decision equal parts surprising and ridiculous. “Mother Schmuckers” is sure to offend some — hell, that’s the point — but it is destined to find cult comedy status.

“Mother Schmuckers” is bowing virtually at Sundance on January 29, with an encore screening happening later in the week on January 31. Head over to Sundance’s website for more info on the premiere. Sign Up: Stay on top of the latest breaking film and TV news! Sign up for our Email Newsletters here.
