Selma Blair recently talked to SciFi Wire on which she said that production on the film has tentatively been scheduled to begin at the beginning of 2007.

 

"I just did The Fog with Revolution, and I was trying to pick their brains for when Hellboy will go," Blair said in an interview. "Apparently [director] Guillermo [del Toro]'s supposed to hand in a script any minute. I know there will probably be a long preproduction, so we'll probably start maybe January 2007."
