Brian Weathersby (Paul Dano) is a 28 year-old salesman at a high-end Swedish mattress company. The afterthought child to elderly parents (Ed Asner, Jane Alexander), and the youngest son in a trio of successful brothers, a shady oil man (Ian Roberts), a surgeon (Robert Stanton), Brian is searching for his place in the world. Unfulfilled by his work he spends a good portion of his day pursuing his goal of someday adopting a baby from China. He gets swept up in a romance with the lovely but misguided Harriet Lolly (Zooey Deschanel) when she comes in to his store one day and falls asleep on one of the beds. To win her over, he must compete with her bear of a father, Al Lolly, (John Goodman) an art-collecting loudmouth with a bad back and deep pockets. "Gigantic" is a funny, surreal love story about the anxiety that comes when two people with crazy families collide unexpectedly and fall for each other.
