Taylor Kitsch movie with handler named Tal

The Doctor, Steven and Dodo land on an alien world in this animated reconstruction of a lost 1966 Doctor Who adventure. There, they meet two peoples; the cutthroat Savages, and civilised Elders, who claim to know all about the Doctor and his travels. Is all as it seems, and will the TARDIS crew come out in one piece if it isn't?

A sister and brother face the realities of familial responsibility as they begin to care for their ailing father.
