From the director of SERENDIPITY and based on the acclaimed novel comes this funny, imaginative film with an all-star cast. By all appearances, Hector (Simon Pegg) has it all - a successful psychiatry practice, a comfortable home and a beautiful, loving girlfriend (Rosamund Pike). However, he's frustrated that he can't provide his patients with real happiness - or even define it for them. So, he decides to travel the world in search of the elusive emotion. From rural China to Africa and even to Los Angeles, Hector's trek is as hilarious as it is enlightening in this richly satisfying comedy that also stars Toni Collette, Christopher Plummer and Stellan Skarsgard.
