io9 showcases artwork by Lorin Wood who worked on the upcoming remake of The Day The Earth Stood Still as a previz animation artist and he drew this sort of Cylon take on the robot Gort, in his spare time only for fun. Apparently, the film makers instead simply updated the classic look of Gort from the 1951 film, without doing a radical reinvention. Still, it's pretty frakking cool and would have made Gort at least a cousin to the Cylons.
The Day The Earth Stood Still comes out December 12 and the cast includes Aaron Douglas as Sgt. Winter and Lorena Gale (Elosha) as Scientist #2. (Mad Men's Jon Hamm also co-stars.)
