It was only yesterday when we shared our love for Michael Dougherty's modern classic TRICK 'R TREAT (and yes, we want to see a sequel! Make it happen, Legendary!) and today we have something TRICK 'R TREAT related to share with you. Below you'll find the creepy animated short SEASON'S GREETINGS, a film produced in 1996 that inspired TRICK 'R TREAT and introduced the world to Sam, the Spirit of Halloween.
