Trick 'r Treat is a classic Halloween movie and must see. We can't get enough of this adorable characeter Sam. Here's some info about his origins: Trick 'r Treat is a 2007 American anthology horror (some comedy) film written and directed by Michael Dougherty and produced by Bryan Singer. The film stars Dylan Baker, Rochelle Aytes, Anna Paquin and Brian Cox. It relates four Halloween horror stories with a common element in them, Sam; a mysterious child trick-or-treater wearing shabby orange footie pajamas with a burlap sack over his head. The character makes an appearance in each of the stories whenever a character breaks Halloween traditions.
