You probably have a grocery run on your to-do list. Maybe laundry. Or a book you've been meaning to read. But if you're Captain America (a.k.a. Steve Rogers), who needs to catch up on a few decades of history, your to-do list likely contains a lot more pop culture than the average bear. A screencap from "Captain America: The Winter Soldier" shows that Rogers has already watched "Star Wars" and may be a burgeoning Apple aficionado. How he's put off watching "Star Trek," though, is beyond me.
