Doug Jones, who played Abe Sapien in HELLBOY, talked with Sci Fi Wire about his role in HELLBOY 2
"The role of Abe Sapien will be beefed up quite a bit for part two," Jones said. "The relationship with Hellboy is going to be more fleshed out. ... The buddy thing ... and conflicts that arise with him are going to be more explored, which I'm very excited about. Abe gets more interaction with bad guys ... [and] has another little sub-storyline that I think is going to be delicious. I don't want to give anything way, but it's going to be a very, very exciting movie to make."
Jones continued,"We've already done two [animated] featurettes of Hellboy, ... [and] I was able to come back and voice the role of Abe Sapien for that. And [director] Guillermo [del Toro] has now ... mentioned publicly that I will be voicing Abe Sapien in the sequel as well."
The voice of Sapien was dubbed in the first HELLBOY film.
Of course, all of this depends on the film finding a new home, something it has yet to do. Del Toro is currently shopping the film with various studios looking for funding.
