We caught up with the filmmakers behind Pixar Animation’s upcoming fantasy Onward at Disney’s D23 Expo on Saturday, who revealed that unlike in most animated films they were able to actually get their main stars together to record -- albeit just once. Onward stars MCU veterans Tom Holland and Chris Pratt as two teenage elf brothers, Ian and Barley Lightfoot, who embark on an extraordinary quest to discover if there is still a little magic left in the world.
