One of the most notable sci-fi characters he ever played was Abe Sapien from an American superhero film Hellboy directed by Guillermo del Toro that is based on Dark Horse comics. He played also his reprised role in the second movie of the original one.
Abe Sapien is a humanoid amphibious creature. He has a pair of gills on his neck, that allows him to breathe underwater, but also has a set of normal human lungs that allows him to stay above and out of water for long periods.
His eyes are covered, doesn’t look as haunting.
Haha he nailed this character coz Hellboy becomes blockbuster hit 🙂
