Teri Hatcher is probably my favourite screen Lois (sorry, Margot Kidder fans);

Yes, mine too. The first series of Lois and Clark was just a delight to watch and the screwball comedy element worked wonderfully. I can't remember the exact line but I always liked the moment when someone said to Lois that she must be the dumbest woman on the planet for not realising that Clark and Superman were one and the same. It acknowledged something that it was impossible not to think *g*.
