The revolving door of directors for JOHN CARTER OF MARS continues to spin. First, I got all excited about Robert Rodriguez, but he left the project due to difficulties with the Director’s Guild. Next up was SKY CAPTAIN director Kerry Conran which seemed like a decent choice although I wasn’t a big SKY CAPTAIN fan. Now the revolving door has spun once more and Jon Favreau (ELF, ZARATHUSTRA) has landed in the director’s chair.
