According to Entertainment Weekly , producers Kathleen Kennedy and Frank Marshall wanted Williams for the part, but due to technological limitations at the time, they couldn't find a way to make the interactivity between his character and a little orphan girl work. "Robin spent a lot of time with us actually doing cast readings and he was hilarious," Kennedy told the outlet. "He would have been a great BFG."The Lucasfilm president said that "figuring out technically how we would do it and whether or not we should try it with to do with forced perspective" was their biggest challenge in bringing the 24-foot giant to life, as "lots of different kind of [digital] effects and techniques were explored."Now, a full two decades later, The BFG is finally making its way to theaters on July 1 with director Steven Spielberg at the helm.
