Comic-Con International: San Diego (SDCC) is massive and thousands will get to see their favorite panels. Even though plenty of people won’t be able to attend the pop culture mecca, fans at home can still see some celebrity panels through Nerd HQ. 

“Heroes Reborn” star Zachary Levi started Nerd HQ in 2011 with the Nerd Machine, an online community website he founded in 2010 to spread the nerd culture. The San Diego event takes place during SDCC but is not connected to the massive convention. While both events are designed to bring fans together with the creators and actors behind their favorite projects, Nerd HQ differentiates itself from SDCC with a good cause and intimate environments.

The event takes place at The New Children’s Museum in downtown San Diego, and the smaller venue has even smaller panels. The sessions, called Conversations for a Cause, allow only 200 guests to watch the panel in the room. The proceeds from their tickets go towards Operation Smile, a nonprofit that helps children born with cleft lip, cleft palate and other facial deformities get free surgeries.

The panels sell out rather quickly for the most part, but fans at home still have an opportunity to watch. The Nerd Machine and IGN will live-stream each panel. With over 30 panels, there is plenty to see, but a few seem a little more exciting than the others. Check out the Nerd HQ panels that fans shouldn’t miss:
