You can be the proud owner of your very own Sammael Rehearsal costume, if you got a few quid to send PropStore.com:
An amazing production made Sammael costume worn by Brian Steele for the John Hurt and Selma Blair movie Hellboy. This suit was made by the Oscar winning special effects makeup artist Rick Baker, who worked on such films as American Werewolf in London, Star Wars, Batman Forever and Planet of the Apes. This is a rehearsal suit worn by the actor for all the set up rehearsals, and would have aided in lighting the film and the positioning of cameras, it would have also been used for practicing the major fight scenes. Made from rubber and painted grey and green. A great display piece!
The pictures below are some cool up-close pix of the suit. I dig the multiple nipples. Nice touch. Thanks to Sammael and Hellmistress on the Hellboard for these links.
