Newly filmed segments of this expanded version of the 1964 finale include
a better explanation of Rice's mission at the start of the movie, and a 10 minute subplot with Anne Helm, who as Lt. Rice's girlfriend plays a completely different character than she did in an episode of the series.
The TV episode itself begins at the 20 minute mark, but there are still several minutes of additional footage, including another alluring female character
( played by Lindo Ho ) later on.
