Those in attendance on the virtual Tudum stage on Saturday included the iconic actors behind several fan-favorite Stranger Things characters Millie Bobby Brown Sadie Sink Finn Wolfhard Caleb McLaughlin Gaten Matarazzo Priah Ferguson Joseph Quinn David Harbour and Joe Keery. 

The cast of the popular sci-fi series kicked off their segment of Saturdays event by competing in a trivia contest with questions about their show submitted by fansand by the looks of it some of the actors might need to brush up on their Stranger Things knowledge. 

They started off strong with a question about which ear Dacre Montgomerys character Billy Hargrove wears his earring to which McLaughlin quickly provided the right answer his left ear. 

What is the password to enter Wills Castle Byers? another fan asked causing the actors to struggle for a bit before Matarazzo eventually came up with the correct answer Radagast.

What movie do the kids sneak into in Season 3 Episode 1? someone else asked. 

Oh I got to know this Im the one who let em in Keery who plays Steve Harrington in the series said in response adding that they must be sneaking into a horror movie. 

Quinnwho doesnt even appear on the show until Season 4 chimed in with the correct answer which was 1985s Day of the Dead. 

But things started to go downhill when trickier questions came in including the exact number of days Mike and Eleven go without seeing each other at the beginning of Season 4 which Wolfhard answered incorrectly. Then no one could devise the correct phrasing for the secret code that Steve and Robin (Maya Hawke) decipher in Season 3.
