So, What About the Ancillary Characters in the 'Live Action' Set Pieces

***** Spoilers ***** Just re-watched this after a few years, and it just occurred to me: almost all of the "live action" set pieces have participants that appear in the scene that culminates in the character's demise. Example: when Det. Roberts "enters" the Mummy's tomb, he meets the Professor, the Egyptian slave, and that hot English chick. Do all of these ancillary characters in the re-created set piece also come to life as monsters intent on destroying the world? It was a little difficult deciphering who was whom during the frantic free-for-all. Also, speaking of Det. Roberts: don't recall seeing his "monster" alter-ego (although we do get to see China's, Jonathan's, etc.); did he make an appearance?
