As you might have known, I bought myself the novel for my birthday last year. The film was already out back then, so the novel I bought had Logan Lerman, Emma Watson, and Ezra Miller on its cover. I read it with the three faces in mind, so when I watched the film, it was already like what I had imagined whilst reading the novel. Logan and Emma made great Charlie and Sam. But Ezra... (OH MY GOD, EZRA!) Well, hands down, Ezra was the actual star in this film. He successfully portrayed the Patrick as gay as I could've imagined. I love Patrick.
Have you watched The Perks?
