* BackedByThePentagon: The British army provided a pursuit launch, a helicopter and a military base for various shots.
* MissingEpisode: Most of "A for Andromeda", as episodes weren't taped by the BBC in those days. Averted with the sequel.
* TheOtherDarrin: Creator/SusanHampshire replaced Creator/JulieChristie as Andromeda in ''The Andromeda Breakthrough''.
* TheOtherMarty: Director Michael Hayes advised the BBC to sign Creator/JulieChristie up for the sequel before she became a big star; he was ignored and the role had to be recast for "Breakthrough".
