*Buck Rogers lasted only two seasons, and the second was a short one at that because of an actors' strike. The more "serious" tone and other changes (like introducing Thom Christopher as Hawk) hurt ratings from the get-go in season 2, and Buck was a goner.
*The book Mike mentions is Buck Rogers in the 25th Century: A TV Companion by Patrick Jankiewicz.
*Buck first appeared in Amazing Stories--no, not the Steven Spielberg anthology series of the 1980s, but the pulp magazine. Phillip Nowlan adapted his 1928 story into a comic strip for the John F. Dille Company in 1929.
*The 1950 TV series ran for 36 episodes in 1950, but the series is completely lost. Eva Marie Saint was one of the actresses who played Wilma in this version!
*Commander Royko in this episode is Christopher Stone, who you can see in our YouTube playlist in a clip from 1970's The Interns.
*Space Vampire is currently the highest-rated Buck episode on TV.com.
