What really amazes me is that the way Zelda talks about the game (and Robin Williams too, though not so much) it seems really genuine. Like she's really familiar with the game, the franchise, and a lot of its tropes (cutting grass, for example). Hollywood people are usually really bad at writing dialogue about games---like, stunningly bad, so I'm left thinking that either they worked really really hard with some hardcore game consultants to prep Zelda and Robin, or they really really are into this game and/or franchise.
