He may have went all over the world in the Mission: Impossible series and then explored the galaxy with his pair of Star Trek films, but an upcoming dramedy will send Simon Pegg on a different kind of mission. Hector and the Search for Happiness, directed by Peter Chelsom (Serendipity), finds the actor as a psychiatrist who attempts to find some meaning in his life by rounding the globe.

Based on Francois Lelord‘s book, it certainly feels sentimental, but hopefully it earns it, moreso than last year’s similar-looking The Secret Life of Walter Mitty. Getting a U.K. release this fall and if distribution comes aboard, we imagine a 2015 release in the United States, check out the trailer below thanks to Collider for the film also starring Rosamund Pike, Stellan Skarsgård, Toni Collette, and Christopher Plummer.

Pegg plays Hector, an eccentric yet irresistible London psychiatrist in crisis: his patients are just not getting any happier! He’s going nowhere. Then one day, armed with buckets of courage and an almost child-like curiosity, Hector breaks out of his sheltered vacuum of a life into a global quest to find out if happiness exists. More importantly, if it exists for Hector. And so begins a colorful, exotic, dangerous and hysterical journey.

Hector and the Search for Happiness opens in the fall in the U.K. but is searching for a U.S. distributor.
