Bachelin's last credited work as a cinema art director was for part two of the US television series Star Trek episode "The Menagerie".[4] Bachelin originally assumed responsibility for art direction for the originally-planned Star Trek pilot episode "The Cage" after the first art director for the series pilot, Pato Guzman, left the production company to repatriate to his native Chile.[5] This original series pilot was turned down by the National Broadcasting Company (the first television network to broadcast Star Trek), and was only released in 1988 as a filler episode in Paramount Television's Star Trek: The Next Generation television series during a writers' strike. Bachelin did not receive screen credit for his work on "The Cage".[6]
