I hope this counts as on-topic for here, and I'm sorry if it isn't! Last night my flatmates and I decided to watch an episode of The Avengers, and we randomly chose the first episode of Season 5, From Venus with Love.
About half way through, a character was mentioned who was a Brigadier, and we geeked happily about that. Then he appeared on screen, and silly_cleo said, "You know, he sounds a lot like Three..."
Hee! I'm rather like that with The Avengers - I saw the reruns on TV when I was a kid and loved it, but I don't remember the plots and hadn't seen it again until recently when I got hold of the Emma Peel episodes. Because it's all about Emma Peel. ;D
I still haven't seen any Sapphire and Steel but I keep hearing about it all over the place. Must watch some!
