In the case of the 1997 special edition releases of the original Star Wars trilogy (episodes IV, V and VI) the twist was the addition of digital effects that weren't possible 20 years before.
George Lucas' decision to add these extra flourishes to his classic trilogy - most extensively in A New Hope - received a mixed reception from fans, particularly the insertion of Jabba The Hut. Some are an amusing addition to proceedings whilst others slightly distract from the experience rather than enhance it.
Still, the remastered sound and vision were spectacular - most notably in the confrontation between Ben and Vader in which their light sabres crackle and spit with an awe-inspiring ferocity.
One of the prominant promotions in '97 were the Tazos that came inside special packs of Walkers crisps. These tapped into the fun of collecting Star Wars trading cards in the '70s, except instead of a stick of gum you got something crunchy to go with your lunchtime sandwich - a ploy that resulted in my eating way too many bags of cheesy Doritos!
