According to the outlet, Rickman wrote a letter while working on 2009’s “The Half-Blood Prince,” titled “Inside Snape’s Head,” seemingly calling out director David Yates.

“It’s as if David Yates has decided that this is not important in the scheme of things i.e. teen audience appeal,” he wrote.

“Just back from weeks away and had to send a line about what you wrote in the souvenir programme for ‘Hallows II.’ Made me very tearful,” she wrote. “Thank *you* for doing justice to my most complex character.”
