"Not every actor is a Tom Cruise. They are not all used to doing big action movies and doing sliding bikes and cars and fights. So you've got to take actors who have maybe not done that kind of stuff and get them through some proper training first."

Of course there's a value in a storyboard if you do a big - let's say an action movie and actors have to move and act in front of a green screen because entire backgrounds exploding and cars flying through there have to be created separately, and in this case you better make sure the actors are precisely placed and the background action is moving in a certain moment, for this type of film you would need a storyboard.
