I was curious about how other countries celebrated Halloween and decided to search the topic. This is what I found:

Jack O’Lanterns.net: Halloween Traditions

My favorites are England and Ireland because of their pagan and Celtic roots.

This A&E special, hosted by Harry Smith, airs every year around Halloween. It tells the history of Halloween dating from the time of the Druidic festival of Samhain to the 20th century. Smith discusses Mexico’s Day of the Dead holiday, and various cities are visited to explore their Halloween traditions and festivities. Also included in the program are clips from horror films such as Halloween.
