Among the guests are, of course, the stars of The CW’s hit shows: Arrow, The Flash, Supergirl, Legends of Tomorrow, and Supernatural.
The Arrowverse shows were grouped together for a panel at EW’s POPFest event, where executive producer Greg Berlanti spoke alongside Stephen Amell, Grant Gustin, Caity Lotz and Melissa Benoist.
Amell is also good friends with Padalecki, and the two actors often post photos together; Amell has helped Padalecki with his social media presence and charity campaigns.
On the Supernatural side, Jared Padalecki and Jensen Ackles were on hand to answer fan questions and chat about the show.
