First of all, huge apologies for my 'disappearance',the wet squib that became of the Championship match with Sirandal, and the subsequent **** around...
I recently made a post and shared an article I found where Joss Whedon shared his top ten writing tips. The first five are here and the full list is on our blog! Great stuff!!!
Joss Whedon is most famous for creating Buffy the Vampire Slayer, its spin-off Angel and the short-lived but much-loved Firefly series. But the writer and director has also worked unseen as a script doctor on movies ranging from Speed to Toy Story. Here, he shares his tips on the art of screenwriting.
Tarzan had the benefit of being easy to translate to film and other mediums. He's just a guy in the jungle. John Carter takes a lot of effects to render the supporting cast alone, much less the vehicles and flora and fauna of Mars.
According to wiki, there were 89 movies with Tarzan in the title between 1918 and 2008. It also doesn't hurt that the idea of the feral child with abilities beyond the normal person is an old and common mythology, so it crosses cultural in generational
I would say that you should pare down your style to a bare-bones style that isn't overly reliant upon a lot of rendering. Focus on shapes, gestures, expressions. Keep the number of panels down per page. Keep a timer handy and give yourself a certain amount of time per task per page. Economize where possible and have a lot of coffee or energy-drinks available!
