Severus Snape

[Carol]

Carol earlier: 
> > I'm just saying that the film version of Snape is based on the
book version and that Alan Rickman, who read the books and knew
Snape's secret long before DH came out (JKR told him) has tried to
stay true to the character depicted in the books even when the scenes
assigned to him are invented by the screenwriter and director.

> I know there were articles that said JKR gave certain actors
information about their characters. However, I'm sure I read a Rickman
interview in which he said he didn't know what was coming. And after
DH, he commented that he finally understood his character's
motivation. I'll look for the interview later this week.

Carol responds:

Right. That was what she told him--not the more complex aspects of his
motivation that we don't know until "the Prince's Tale" or can infer
from his other actions throughout the series. He's still interpreting
Snape on the basis of what he knows. I wonder what he and Michael
Gambon (who hasn't read the books!) thought about the scene on the
tower, which was filmed before DH came out and consequently before
Rickman fully understood Snape's motivation! I would love to have
overheard the conversations between those two and David Yates as it
was being filmed. I just hope that the ambiguity remains even though
we can guess what the majority of filmgoers who haven't read the books
(or online spoilers) will think.

Carol, who would appreciate a link to the Rickman interviews since she
mysteriously lost all her bookmarks a few weeks ago
