The 5th episode of "not a fan" requires one of the characters to have a two year-old son. My two year-old son nailed the aud-ish. Actually, there was no audition. They just kind of cast him.
Anyway, here's a brief snippet of his behind the scenes antics. My personal favorite: flying like Buzz Lightyear.
Note: The audio, for some reason, is out of sync. Perhaps it will improve as the video undergoes more processing. If not, it really doesn't matter as no one speaks on camera after the first ten seconds anyway.
