Pulling off a directorial debut is something I imagine is far from easy for most people.
You need a cast and crew that not only trusts you, but is also talented in their line of work. True, actors who turn directors more than likely pick up some tricks from others they have worked for in the past, though the great teacher known as experience is something yet to be obtained. Perhaps most important, the story they want to tell has to be not only possible to film, but personal to them.
Nothing else to say
