Paul Rudd (I Love You, Man, Forgetting Sarah Marshall) is one funny guy when he puts on his "everyman" persona and displays how oblivious he can be to his surroundings. Rudd plays the Idiot Brother, Ned who is playful and as adorable as a stray puppy. He also has lost many of the neurons in his brain due to the fact he's been a "stoner" most of his life. His three sisters decide to help him out when he is released from jail. Ned's best buddy and the one who understands him best is his dog, Willie Nelson.his script was written for Rudd and fits him like a glove especially due to his comedic timing which is spot on. While he gets help from his sisters he is somewhat of a guardian angel for them as well, helping them fight off harmful demons of their own. Zooey Deschanel (Yes Man, Gigantic) is his sister Natalie, Elizabeth Banks (Modern Family, Scrubs) is another sister Miranda, and Emily Mortimer (Shutter Island, Cars2) is the third sister, Liz. The viewing audience can see what's ahead for poor Ned so tension builds as he bumbles his way into troublesome scenarios.
