Writer-director Michael J. Bassett's "Silent Hill: Revelation 3D" has expanded its supporting cast, signing Radha Mitchell, Sean Bean and Deborah Kara Unger, according to Variety.

Shooting on the sequel kicked off this month in Toronto. The film is based on the acclaimed survival horror video game created by Konami.

Mitchell stars again as Rose Da Silva, and has appeared in "The Crazies" and "Surrogates."

Bean, who plays Rose's husband Christopher, will star next month in HBO's fantasy series "Game of Thrones" and has past credits that include "The Lord of the Rings: The Fellowship of the Ring," "Sharpe's Peril."

Unger's recent work includes "Takedown," "Shake Hands With the Devil." She returns as Dahlia Gillespie.

Also aboard the sequel are Adelaide Clemens ("X-Men Origins: Wolverine") and Kit Harington ("Game of Thrones").

Davis Films' Samuel Hadida and Don Carmody ("Resident Evil: Afterlife 3D"), who teamed with director Christophe Gans on the original film, will once again produce.

"Silent Hill: Revelation 3D" will follow a teenage girl and her father who are hunted by supernatural forces. On the eve of her 18th birthday, the girl discovers a shocking secret about herself as her terrifying nightmares intensify and her father goes missing.
