Last night, in celebration of their 200th episode, the cast and crew of the CW’s Supernatural treated 200 lucky fans to an advance screening of next week’s episode. Writers and stars of the show participated in a live panel discussion and Q&A as a surprise to the fans. They also experienced an interactive tour of Mack Sennett Studios’ basement and found themselves in an art gallery in Mabel’s Speakeasy featuring artwork from the show. Execs from The CW joined in on the fun which included catering by Boyz In The Kitchen, freshly popped popcorn, and two surprise live performances in the newly remodeled Woodshop. This event was top secret so no photos were allowed (other than a few Instagram posts we found posted by the fans themselves…Shhh!)
