Which came first, the spy or the sex appeal?
It's hard to tell, really, but looking at our selection of Sexy Saturday spy shows which features spies who turn heads when they walk by, it might be a toss up.
We have Chuck, for example. There's no doubt Sarah was going to catch your eye whether she was a spy or not. Chuck, on the other hand, gained confidence and sex appeal the longer he was in the biz. The same could be said for Maxwell Smart and Agent 99 of Get Smart.
Then we have both sets of Nikita and Michael on La Femme Nikita and Nikita. They're looking good no matter their profession. The Americans' Philip and Elizabeth Jenkins can turn on the charm or blend into the background, as good spies should be able to do.
Which begs the question, shouldn't many of these sexy spies tone it down a bit more often in order to get the job done? Aren't spies supposed to be more every man than hottest cat in the room?
Flip around our slideshow and let us know who you think would be the best at their job, who you'd recognize first and who should probably just give it up and go home; they're no way they're going to go undetected!
