.you must be mad, or else you wouldn't have come here

I WISH I'd have known about her in Doctor Who then - it would have added an interesting layer of lulz to the whole tale. :P
I don't think the Who connection was needed to give some lulz to it - the rest of my class spent the whole time giggling, especially whenever Jacobi opened his mouth. After a while, I realized why that was - as a disciple of Laurence Olivier, Jacobi followed the "melancholic Hamlet" way of playing the character, and for my dunderhead schoolmates that interpretation was funny. Personally I couldn't see the funny in it, though "melancholic" is not my way of viewing the character; when I first read the play, I read his lines in the "f***ingly pissed off Hamlet" way of playing, which is probably another reason why Mel Gibson's rendition is my favourite - he does great "f***ingly pissed off".

& I think she had a very good look for it - she always looked (& still does, I think) so delicate & ethereal, like a little spacefaery.
That's a good interpretation of the character, yes, and Lalla fitted it to a T. In the Mel Gibson version, Ophelia was played by a very young and pixie-faced Helena Bonham-Carter, who looked just perfect in the role, especially after the poor dear went mad. She was very peaceful and waif in that scene, while Lalla went for the "f***ingly pissed off" rendition - I remember her singing the mad!Ophelia songs as if she wanted to strangle everybody in the room.

THEY WOULD. Then they'd probably end up fighting it out, & in the end, the Doctor would be like, 'I'm sorry I took over the world, here, have it back!' ::runs into the TARDIS & dematerialises:: Or Five would, anyway. ::giggles::
The others would too, I think - it seems like a thing Nine or Ten would also do, anyway.
