Considering a lot of directors in the industry, the actual skill level needed for the job is something a monkey must be practically able to do. I wouldn't advise it for your friend. There would be too much competition already in an area where actual skill doesn't matter that much, and it's an industry where things like job security and success are fleeting things.
In another words if for some reason he does somehow get into it he better have a plan to be able to jump out of it into something else quickly if need be.
