 In filming the Well of Souls sequence, the producers scoured every  pet shop in London and the South of England for every snake they  could lay their hands on. Hence there are snakes that are  identifiable from many different geographical areas. However, once  all the snakes were on set, it became clear that there were not  nearly enough of them, so Steven Spielberg (I) (qv) had several  hoses cut into lengths, and these were used as well. Looking  closely, you can tell which are the real snakes and which are not.
