Extended = extras, movie bloopers, how they did makeup/costumes etc, interviews with actors or sometimes just extra scenes in the movie that make the movie longer (they usually cut them out for reg TV broadcasting)
regular = movie minus all the above
Pirates of the Caribbean extended/special edition is fun to watch regarding the special effects of the skeleton crew and the freaky monkey!
TPBM likes to watch horror movies ALONE IN THE DARK..lol
Clippityclop is finally getting to spend some time in the saddle!
