In plays...out of necessity...you have to deal with language and ideas,
whereas converting ideas into visuals involves using a whole different
part of your brain. There is a transition to be made there. So, I
suppose I would encourage any writer to write a play, for a number of
reasons. First of all, because it forces you to deal with ideas rather
than just blowing things up, or creating special effects. I think any
good film has to have some significant human idea at the heart of
it.
