Elijah Wood
CGI has advanced considerably since the filming of The Lord of the Rings films. Actors do not require size doubles now, as they did in the past – the CGI team can simply insert an actor’s face onto a hobbit’s body.
However, for scenes in which Elijah’s character had to interact with larger characters than himself in size, they still required doubles of regular-sized actors. It’s fascinating to see these pics of Big Frodo and Little Frodo together!
