In the series, Jonathan Rhys Meyers ("The Tudors") stars as the title vampire, who pretends to be an American businessman named Alan Grayson. He attempts to build a business empire and simultaneously get revenge on old rivals in Victorian London, only to have his plans complicated when he falls for Mina ("Arrow" star Jessica DeGouw).
McGrath -- who also appeared on "The Tudors" -- will play Lucy Westenra, Mina's best friend, who is drawn into the lustful, dangerous world around her.
Anozie will play R.M. Renfield, Dracula's righthand man who keeps the lord's secrets safe.
"Dracula" is the brainchild of Tony Krantz ("24," "Sports Night"), former HBO Films president Colin Callender and writer/co-exec producer Cole Haddon. The series will air on NBC in the U.S. and Sky Living in the U.K. Gareth Neame ("Downton Abbey"), Anne Mensah and Reece Pearson, will also serve as a co-exec producers.
"Dracula" is set to premiere this fall.
