"Praise be to the casting gods, because Bill Heder in a Roald Dahl film is perfection. If this was going to be an animated film, we'd say to just have all the non-BFG giants voiced by him. Deadline reports that Heder is joining the Steven Spielberg-helmed film as one of the giants. Spoiler alert: All of them except the titular Big Friendly Giant are human-eating bad guys. Part of the plot revolves the BFG (Mark Rylance) and a young girl named Sophie (Ruby Barnhill) convincing world leaders that something needs to be done about the danger they pose." - Jessie

Looks like they meant Bill Hader. - Jessie
