This episode is a clip show episode featuring:
This episode incorporates elements from This Is Your Life (1955), for which APF was required to obtain approval from the programme's creator, Ralph Edwards. Negotiations with Edwards were slow to progress, so work began on an alternative clip show in which the main characters watch film recordings of some of Stingray's past missions. Production on that episode were halted when AP Films received permission to proceed with "Aquanaut of the Year".
The first Gerry Anderson series to include a clip show. This would be followed by the Thunderbirds (1965) episode Security Hazard (1966), the Captain Scarlet and the Mysterons (1967) episode The Inquisition (1968) & and the Joe 90 (1968) episode The Birthday (1969).
