The episode was subsequently expanded with additional footage and released in colour as the feature-length movie, To Trap a Spy.

The episode opens with several THRUSH agents raiding the UNCLE headquarters via a covert entrance from the back of a common tailor shop in New York City.

A sequence in Solo shows the death of the captured agents due to THRUSH having them take a slow acting poison killing them regardless of the success or failure of their mission.

The producer was Norman Felton who had conceived the original idea for the show and then developed it in consultation with the creator of James Bond — Ian Fleming.

The score was composed by Jerry Goldsmith including the catchy theme tune which was performed by The Gallants in a later episode and released as a 45 single.

[1] This first episode features Napoleon Solo as the eponymous Man from U.N.C.L.E., as the series concept was to focus upon this individual agent as the hero.

The Russian agent, Illya Kuryakin, only has four lines in this episode as the role had yet to attract the attention which it subsequently achieved due to the casting of David McCallum, who was a great favorite of female fans.
