I’ve heard some speculation that Tom Hardy might be portraying a werewolf (or similar creature derived from African mythology) in the upcoming FX miniseries Taboo, but I don’t think so. From Variety:
Set in 1814, “Taboo” follows James Keziah Delaney (Hardy), a man who has been to the ends of the earth and comes back irrevocably changed. Believed to be long dead, he returns home to London from Africa to inherit what is left of his father’s shipping empire and rebuild a life for himself. But his father’s legacy is a poisoned chalice, and with enemies lurking in every dark corner, James must navigate increasingly complex territories to avoid his own death sentence. A dark family mystery unfolds in a combustible tale of love and treachery.
There’s enough going on there that an explicitly supernatural angle would overload the plot. The flash of a bloody-mouthed someone (or something) in the trailer is more likely a reference to a crazy experience Delany had during his lost decade in Africa, or cut in from a scene depicting the “madness” plaguing his family. Although Hardy would make an excellent werewolf, don’t you think?
Taboo is an eight-episode miniseries co-produced by FX and BBC One. As of today it has no official release date.
