Thanks guys for your commnts and answers, the reason of asking this question is I always find people under estimate screenplay writers in the showbiz field, I agree with you that being a director will give you more space to implement your thoughts and ideas on the screen but if you ever grabbed a screenplay and read it you will be able to draw the whole movie in your imagination, screenplay writeres are very talented in describing characters scenes and making the whole plot in words only.
I'm not saying directing is nothing but a translation to the movie script but I say movie script is the first step and the most important one in making a movie so I prefer to be a writer and I think writers must have the same appreciation as directors.
DISCLAIMER: Now after shouting out my opinion I want to say that I'm not affiliated with screenwriters guild in any way, in fact I never finished a movie script but once I will and then I want my name to appear just beside the director's :P Walid I may give you a role in the movie ;)
