Good Morning!
Why, Oh, Why am I not in bed yet?!?!?!
Ah, well...
I adored the young boy in "Cinema Paradiso", and also in his subsequent performance in another film - sorry both the name of the child actor and the other film escape me right now... Hey, give me a break, it's 4:15AM here in Richmond, VA?!?!?

There are a few others, however, I've always admired the work of any child actor in any horror film. I just have to wonder if the studios ever keep psychiatrists or some other sort of professional on set should the need arise. I don't know how Linda Blair did it in "The Exorcist". As well as the aforementioned Hayley-Joel Osment in "The Sixth Sense".
Osment? Osmond? -Someone needs to get to sleep....
I'll come up with more specifics as soon as I wake up later today.
Oh, and BK - the Monty Python's "Spamalot" - is that the title of the piece? - sounds very interesting. I remember reading the casting breakdown - very eclectic to say the least.
Good Morning, and Goodnight.
