Culp and Cosby were a cool-headed team on this show. Loads of plot, unlike today's 'set up the explosion/chase/fight' shows. And Cosby played the educated one (a real breakthrough for an African-American). That education comes in handy.And let's face it: if the internet had existed back then, they'd both have estrogen brigades.

To the critics of the plot:This is exactly the kind of thing that either side might have tried to pull during the cold war. The plot is only slightly exaggerated. It looks fictitious now because our memories are very short, and because China is ruled by slightly better people these days. But believe me, this plot was entirely too plausible during the cold war, although it would have been more plausible with the Russians, the Chinese were extremely antagonistic of the US as well, particularly in the 60s with US forces assaulting Vietnam, well inside China's traditional sphere of influence.Also the Chinese government under Mao did far worse things than what is depicted in this episode.

Loved the series as well as it's ground breaking feature with Bill Cosby.

This was hilarious, the PRC is trying to killll youuuu! Granted, relations between China and the US haven't always been so great (unfortunately), but this was just crazy. I can't get past how awful this episode was to even try another. All Chinese peepole want to gets you, yeessshhhh.. We crafty Asian man!

I loved I Spy. Used to watch it with my dad when I was a little kid. I forgot all about this show until I saw it listed tonight. Kept a smile on my face the whole episode. Love to have some of these old shows back. Robert Culp & Bill Cosby are first class here. Great show.
