Please tell me whether Fibonacci's "bubbling B's" were adlibbed, or part of the direction? That is such a fantastic element of the VO I couldn't help but take a moment when I first heard it to laugh and appreciate the detail put into this update.
Neil brought that from hour one. The high-level umbrella direction in the script was 'Stephen Fry without the generosity'. Wattle-shaking, bloviating, was all in there, but Neil turned up on the first call having deconstructed the character's physicality and used it to inform the vocal approach. The blubbing, the pops, the 'bipeds' insults, a lot of the little stings and flourishes at the end of some lines are all Neil just having fun and my encouraging him to try different things and make it his own.
