James Cameron and Sam Worthington are already set to reunite for two sequels to Avatar, but that's apparently not enough for Fox.  Heat Vision reports that the studio has picked up a pitch from writer Will Staples called Myth, and wants to bring Cameron, Worthington, and Transformers producer Lorenzo di Bonaventura together on the film.  However, at this stage, Cameron is only attached to executive producer with di Bonaventura and Worthington attached to produce, although no deals are final.  Cameron would not direct and Worthington hasn't made a commitment to star.  Nothing is known about Myth other than "it's big, it's sci-fi, and it's got lots of action."  Riveting.The talent involved at this stage is still fungible at this point but Staples is attached to write the script.  Staples' biggest claim to fame at this point is having served as a writer on the popular Call of Duty video game series.  He, along with writing partner Sean O'Keefe, also wrote Apaches for Jerry Bruckheimer and World's Most Wanted for Neal Moritz.
