English Science Fiction Magazine SFX reported the following:
SFX can blow one at least one rumour out of the water. Timothy Spall is not cast, despite internet gossip that he would be playing dwarven warrior Gimli, a role he would admittedly be well suited. When we asked New Line, they said “where did you read that? We know nothing about it.” We also rang his agents, Markham and Froggatt Ltd, who informed us Spall is currently filming in France and was unavailable for comment. They assured us “he’s not been cast, really, we’ve not even had an offer.”
I guess the only sure thing we can count on these days is that Wood and Astin are in the movie.
