Thunderpants

Life is a gas — literally, not figuratively — for poor Patrick Smash (Bruce Cook), whose gastrointestinal condition leaves an invisible cloud of odor constantly hovering around him. The smell drives everybody away except his friend Alan (Rupert Grint), who has no sense of smell. With Alan’s help, Patrick pursues his dream of becoming an astronaut and, along the way, learns the scent of both fame and infamy.
