Selma Blair is joining the cast of the film adaptation of Hellboy.

She will join Ron Pearlman who is playing the title character in the film which is being directed by Guillermo Del Toro.

The film is based on the Dark Horse comic character.

Hellboy is set during the final days of the Second World War and is about how the Nazi's attempt to use black magic to help their cause.

The Allies raid the camp where the ceremony is taking place, but not before a demon, Hellboy, has already been conjured. Joining the Allied forces, Hellboy eventually grows to adulthood, serving the cause of good rather than evil.

Accompanying him along the way are other agents, including Liz Sherman, a woman who can psychically control fire. Sherman will be played by Blair.

Filming is due to begin in Prague in March.
