This extra is the highlight of the new set, and so much fun that fans of the series may want to jump to it first (if you're new to the show, save it for last!). It's basically a table read of an unproduced script for a reunion movie that Billy Mumy co-wrote (along with Brian Greer and Paul Gordon) back in 1980. Mumy, Mark Goddard, Marta Kristen, and Angela Cartwright reprise their original roles for this table read, and are joined by some of their friends and family for some of the other roles (including Guy Williams, Jr. and Veronica Cartwright). This extra includes an optional intro and 'outro' by Billy Mumy. (thetvdb.com)
