Toni Collette and Jean Reno are set to star in Hector And The Search For Happiness, a romantic comedy feature directed by Peter Chelsom that follows a psychiatrist as he searches the globe for the definition of happiness. The addition of Collette and Reno completes the casting and the film has just commenced principal photography, Deadline said.

Collette and Reno join a stellar cast that includes Simon Pegg, who will play Hector, an eccentric London psychiatrist in crisis; Rosamund Pike; Stellan Skarsgard; Christopher Plummer; Desiree Zurowski; and Jakob Davies.

Chelsom and Tinker Lindsay wrote the screenplay, adapted from the novel of the same name by Francis Lelord. The film is produced by Judy Tossell for Egoli Tossell Film and Christine Haebler for Screen Siren Pictures. Jens Meurer and Trish Dolman are serving as executive producers.
