A number of internet video stores (including iTunes) have let you pre-order movies for a while, but not Google Play -- you've had to mark the release on your calendar to get a hot flick ASAP. Don't worry about being so dutiful in the future, though. Google has switched on movie pre-orders for Google Play users in the US; you now just have to find the title you want to see and click a button to reserve it. Other countries will get the feature "soon," Google says. It's a pretty straightforward addition, but it could be very helpful if you're determined to score a copy of Gone Girl while you're still in the theater parking lot.
