Robert Rodriguez writes, directs, produces, shoots, scores and edits his movies. He even cooks the meals for his cast and crew. He's a true Renaissance man. And I hate him for it.
His ten minute film school featurettes on his DVDs make it all seem so easy. And with the easy access and affordability of movie making hardware and software, everybody believes him.
Now far be it from me to discourage the next budding Robert Rodriguez. But when I meet a multi-hyphenate, my first thought is: Jack of all trades, master of none. And I meet them all the time.
