While I do admit being familiar with the source material, and am only as far as the courtroom scene, I could imagine a good director being able to make a silent film using this and no intertitles at all.
The question is, who would play Crono?
Consider this a CT Movie "Casting Call"...
Edit: While I normally respect everyone's opinion, anyone suggesting anything other than Henson's Creature Shop for Robo should have a rather good argument as to why not them. :P
