Risk of remaking an already successful movie is far less than making an original screenplay. That's why I'm always so critical of scifi. I read a LOT of it and most of what makes it to the screen is only so-so and than heavy on monsters and gore.
The remake thing? Well, that leads to endlessly repetitive franchise stuff with maybe a half dozen scripts being endlessly recycled. Avatar, for example, was beautiful to look at but not very 'original' in the writing department. But, boy, did they ever sell tickets. James Bond franchise stuff is.......comfortable.....and predictible.
Wanna get together and do an orignal screenplay? I've got a couple jam-up ideas.
