This short film by Tim Mason is absolutely uproarious. It captures so many of the absurd aspects of voice acting gigs: the mind-numbing repetition, the dubious acting direction, the bored but patient sound guy, the willingness of the voice actor to press on no matter what.
Also, love the juxtaposition between what’s unfolding in the booth and the nonsense outside of it. This incongruity often exists in real life too, albeit not in as extreme a fashion.
