When In Rome Has Such An Intricate Plot, It Needs To Be Explained To You In Great Detail

I don't know about you, but when I saw the intensely yellow posters for When In Rome, I was so confused it was more like Wha? In Rome, you know?
Did David Lynch direct this? It's all just so strange and complex, like a puzzle, or a 1001 pieces puzzle. So I guess Kristen Bell drives a taxi? A tiny taxi? In Rome? And Fergie's husband proposes to her, because the movie was made by the same studio as The Proposal, which means there's a proposal in it, right? I had to sit down and stare at a fixed, non-retina-searing-yellow point because the thoughts were just coming so quickly it was making me dizzy.
Then I saw the When In Rome trailer, which only made things worse. Apparently, the movie has nothing to do with taxis or proposals. Instead there's something about a fountain and magical coins and a wedding and breath spray. It makes no sense. Like cubism. I'm pretty sure you'd need a degree in Italian studies—or at least a copy of Let's Go: Europe—to understand it completely.
