Apparently, moony prefers Giles to Searle (see other Tattoo thread )
Big Sis had 2 books by Searle back in the late 50's but they got lost somewhere along the way. I was delighted to buy one of them in a very large second hand book stall not far from me :o)
I'm afraid I didn't see the remake. I can't imagine anyone as the headmistress other than Alaister Sim, even though I do like Rupert Everett in other films. Unconditional Love being one of my favourites.
