Ken Jeong was a judge from the US version of "The Masked Singer". Joel McHale is a good friend of Ken and co-star. Alison Brie is an actress from Hollywood, married to Dave Franco and has cutie kittens.
"When are they now?" There's neither Glover, nor Gillian, nor Chase, nor the dean... ^^; but hey, maybe McHale and Brie are enough. Oh, and... Brown isn't supposed to be that thin. It kinda changes the character a bit. I guess they'll have to explain said change in the movie.
