After posting the birthday, I looked him up on imdb to check the birthdate. And, a promo came up - he's about to be in a movie "Todd Tarantula" (and is also listed for a couple of upcoming things in 2024). When I looked up the movie, the notes said that it's been in development since 2011 and was originally announced in 2013 for production to begin in 2014. They listed who that cast was to be, and Christopher Pennock was originally to be in it - and it was the same part that Selby ended up doing!!!! I can't picture them both doing the same part. Really quite a coincidence that it would work out like that.
