Perhaps it would be a good idea to add a 'Bodily Explosion' category to this site (or something of a similar name). This could be added to all the deaths that involve a character literally blowing up, therefore separating them from other characters who die in actual fiery explosions. Characters who would qualify here would include Mr Creosote, René Belloq, Dr Kananga, Milton Krest, Emil Antonowsky and even Sauron, to name a few.
For anyone who's watched Big Trouble in Little China, you'll find this category would be perfect for the character Thunder...
