This motion picture originally aired on NBC@10:00 p.m. (EST), Friday, February 4 and Friday, February 11, 1966 as the 49th & 50th episodes of The Man from U.N.C.L.E. (1964), "The Bridge Of Lions Affair" (Parts 1 and 2).
The Age Reversal machine, seen several times, appears to be the top part of Robbie the Robot from Forbidden Planet.
The film was completely rescored by Gerald Fried, because the TV version used cues from earlier episodes which could not be relicensed for theatrical.
For unknown reasons, the scenes with Wanda, played by Leigh Chapman in the TV version, were refilmed with Yvonne Craig.
Jordin's willingness to occasionally help Solo, despite being a THRUSH agent, may initially seem confusing. The TV version explained that he too was searching for Lancer, but that scene was inexplicably cut from this version.
