Some of the options even let you start a video chat while watching the movie. You can usually minimize this if you want to focus on the movie, but you might miss out on some hilarious running commentary if you do. Once you get up and running, most of these services let you chat to your friends in a chatroom at the edge of the screen. That said, some platform specific services, like Disney+ GroupWatch, work anywhere you can use the app. If you planned to watch a movie on your TV, you should work out how to cast your computer to your TV before getting started. What’s more, the majority of these services only work on a computer and many of them only work with the Google Chrome browser. If you’re hoping to watch Netflix together, you all need to have your own Netflix subscription.
