Syfy’s epic adaptation of Arthur C. Clarke’s Childhood’s End has added further stars to its cast.

Former Fantastic Four foe Julian McMahon (he played Doctor Doom in the FF movies a few years back) and Daisy Betts will be appearing alongside Mike Vogel, Charles Dance, Ashley Zukerman, Osy Ikhile and Yael Stone.

McMahon will play Rupert Boyce, an enigmatic American entrepreneur, while Betts has been cast as an arts graduate engaged to Ricky Stormgren (Vogel), described as “the most influential human in the world”.

The script is by Life on Mars’ Matthew Graham and is being directed by The Time of the Doctor’s Nick Hurran. The six hour miniseries is being filmed in Australia.
