Go for Zucker! (Alles auf Zucker!) 2006

Down on his luck, conniving pool shark Jaeckie Zucker must make up with his estranged Orthodox Jewish brother Samuel in order to meet the terms of his mother's inheritance - the only thing that could save him from jail, ruin and divorce. But as Samuel and his entire clan move into Jaeckie's chaotic household, a clash of civilizations is inevitable, and Jaeckie's going to need every trick he can think of to make things go smoothly.
