Amy Schumer will star in a live-action Barbie movie, which is a real thing that Sony is really producing. According to Deadline, the premise of the movie is that the main character — and Schumer's role — gets kicked out of "Barbieland" for not being perfect enough, and ends up stuck in the real world (just like Amy Adams in Enchanted, except probably with more cussing). Her adventures in reality teach her that perfection comes from within, and she returns to Barbieland just in time to save it with her newly empowered views. No, really.
Schumer and her sister Kim Caramele are also apparently planning to rewrite the movie's script from an original draft by Hilary Winston (who's worked on TV shows like Community and My Name is Earl). The Barbie movie has actually been in development since early 2014, when Sony made the initial deal with Mattel.
2016 is maybe just trolling at this point? ¯\_(ツ)_/¯
