I was hugely flattered that they came to me first regarding this guest appearance... But I actually declined, because I just wasn't sure what the appearance would entail, and because they had to shoot during San Diego Comic Con where I already had a plate full! The production company was super nice and kept asking me over several days hahaha, including explaining to me in details what the shoot would be, and finding a way to jet me up to LA from San Diego the Friday of SDCC. The entire crew was extremely professional and kind.
I found out later who my co-judges would be (to my delight).
During the episode, we talked directly to the contestants and gave them a lengthy critique. I liked Danielle's costume the most because there was so much hand work done on it, compared to some of the other costumes being put together from found pieces. Yes, Celeste's cube was also well constructed!
I was thoroughly impressed by George Takei's and Adam Busch's professionalism and respect toward cosplay. Thumbs up, gentlemen!
