Scener and Netflix have partnered to host a virtual watch party premiere of the final two episodes of “Stranger Things” season 4. As the clock approaches midnight, fans can countdown to a worldwide watch party event with some of the series’ stars, including David Harbour, Brett Gelman, Joseph Quinn and Jamie Campbell Bower, and Netflix Geeked host Terri Schwartz.

The cast will join fans for a live video Q&A that kicks off this Thursday, June 30, at 11:30 PM PST. Find out what songs the cast would play to fight Vecna’s curse. Learn about which scenes were the most intense to film. Bounce off theories about the Upside Down being stuck in the past.

The live Q&A with the cast will be followed by the virtual screenings of Episodes 408 and 409 in a custom-curated theater built to host thousands of guests. In addition to real-time reactions from their favorite stars on camera, fans can also connect over live chat messenger while seamlessly streaming both episodes over synchronized playback.

Signing up is free, and joining is simple—download Scener’s Google Chrome extension for desktop or laptop viewing. Participants in the U.S. can also use Scener’s new mobile app and sync it to their television to watch on a larger screen. To participate, RSVP at strangerthings4.scener.com.
