Silicon Valley Comic Con will unleash its third iteration April 6-8 at the San Jose McEnery Convention Center, and the lineup of announced guests should make nerdy hearts melt all around the Bay Area.

Marvel Comics legend Stan Lee, who initially launched Silicon Valley Comic Con with Steve Wozniak in 2016, is set to return. Lee’s had health problems recently, but he took to social media to let fans know he plans to be in San Jose. Excelsior!

The first women of color to go to space — both fictional and in the real world — will also be there. On April 7, Nichelle Nichols, who broke barriers as Uhura on “Star Trek,” will introduce astronaut keynote speaker Mae Jemison, who will talk about her experiences as a space voyager and her plans to be part of an initiative for humans to travel to another star within the next century.

“Star Wars” fans won’t be left out, with a saga-spanning panel April 6 that features Mads Mikkelsen (Galen Erso), Ian McDiarmid (Emperor Palpatine), Ray Park (Darth Maul), Temuera Morrison (Jango Fett), Daniel Logan (young Boba Fett). It’ll be moderated by Gary Whitta, co-writer of “Rogue One: A Star Wars Story.”

Fans of Netflix’s “Jessica Jones” series have a double treat in store as both title star Krysten Ritter and David Tennant, who plays her nemeis, the Purple Man, will be on hand. And for those who still remember Tennant fondly from his days as the 10th Doctor on “Doctor Who,” one of his co-stars, Freema Agyeman, will also be at SVCC.

This year’s theme, “What Does It Mean to Be Human?” will be tackled in a couple of keynote speeches. One features author and TED creator Richard Wurman and musician Kevin Eubanks. The other is a conversation with famed physicist and futurist Michio Kaku on the future of humanity.

The bad news: Jeff Goldblum, who had a memorable role in “Thor: Ragnarok” and will be in the upcoming “Jurassic World: Fallen Kingdom,” had to cancel his appearance.
