Hellboy's gun was given the name "Samaritan" for the film to illustrate the BPRD's techno-magic. Del Toro approached the love story with a reverse Beauty and the Beast approach, stating, “I wanted the beauty to turn into a beast in the end to fully assume her mortal gifts... and when she accepts herself for what she is, a monster, then she can love the monster .” The idea of Hellboy spying on Liz and Myers was originally written for a separate script titled ‘’Meat Market, A Love Story’’. While Broom’s death happened early in the comics, Del Toro wished to delay it to have audiences become attached to the character and “make it painful to lose that character.”
