Joss Whedon and all the writers of 'Iron Man' and 'Thor' found a way to keep Coulson saying something that keeps you guessing. I'm really lucky because a lot of people play agents and don't get nearly as much fun stuff to do.
A few of these interviews have gone slightly awry, because every now and again there has been the odd conflict of interest between interviews because of the Iron Maiden record, and I am a bit long-winded.
Their every instinct - and I have to say this is without exception - is to iron out the bumps, and It's always the bumps that are the most interesting stuff.
