Since the book We Were Liars was published in 2014, there have been no announcements about a movie adaptation. However, that doesn't necessarily mean that a movie adaptation isn't in the works. It's possible that a studio or filmmaker has optioned the book and is in the early stages of development, but no news has been announced yet. If you're a fan of the book and would like to see a movie adaptation, your best bet is to keep an eye on entertainment news outlets for any announcements.
