What [statistically speaking] is the most common "next job" for FILM DIRECTORs, when they cant get work direct?

there isn't really any statistics involved about the "next job" but as far as i know filmmakers never really stop making films. Nowadays if one project is not available there is always another one to go to and you must remember that directors these days can set up their own films (mainly through their production companies). Some directors go and do tv commercials (David Fincher did a nike commercial and Brett Ratner did the Guitar Hero World tour tv ad) or they go into TV proper (Frank Darabont did some episodes for The Shield). Others simply bide their time researching for another project, look at James Cameron, hasn't made an actual film since Titanic but spent the time between Titanic and Avatar researching the capabilities of 3-D.
