I recently mentioned the release of A two disc 'collectors edition' of Bram Stoker's Dracula. I haven't seen this dvd, but Belgian newspaper De Standaard today claims the extra's contain the death scene of Renfield (played by Tom Waits). I don't remember this being in the original theatrical release - although I could be mistaken.
UPDATE: "Renfield's death was in the original. It involved Renfield being hurled around his
cell by whispy plumes of smoke and banging into the bars and walls." (Neil)
UPDATE 2: "I can say without a doubt that Renfield's death was never part of the theatrical release. I also have the Superbit DVD version of the film, and I'm certain it wasn't included on there either." (Kevin)
