The subplot involving an actress trying to win the role of Bond's wife in a film version of On Her Majesty's Secret Service references the fact that OHMSS was originally scheduled to be the Bond film released in 1967 but You Only Live Twice was produced instead.
Welcome to Japan, Mr. Bond is both a quote from and was also a tagline for the James Bond movie You Only Live Twice (1967) which this documentary is a promotional television special for.
Featured on the the DVD of You Only Live Twice Ultimate Edition.
The actors who played Moneypenny and Q in the Bond films reprise their roles for this special, which was partially filmed on the MI6 sets featured in the movies.
