Rob Long is watching a Satyajit Ray film on Criterion while eating ice cream and staring at his phone — which means he is, essentially, just eating ice cream. Rob is a pro at keeping his head down. Writers do it at auditions, following along with their own words instead of watching what actors are doing to them. Which turns out to be expensive, because the two actors who read “You’ve heard of me” as completely opposite character choices taught the writers something their script didn’t know yet. Heads down feels productive. Heads up is where the show actually lives.
