"Star Trek" icon William Shatner, "Deadpool" director Tim Miller and "The X-Files" creator Chris Carter will converge in Washington, D.C., next week for Smithsonian magazine's fourth annual "The Future is Here Festival."

The three-day event spotlights the most advanced thinking in science, technology, space, art and engineering from experts, visionaries and noted science-lovers.

The festival will kick off Friday, April 22, with a ticketed event with Shatner celebrating the 50th anniversary of "Star Trek," a conversation with Carter, and an exclusive preview of the second season of Syfy's "12 Monkeys," presented by stars Aaron Stanford and Amanda Schull and executive producer Terry Matalas.

Miller, the co-founder of Blur Studio in Los Angeles, will appear as part of the weekend programming. Other speakers include "The Martian" author Andy Weir, explorers Céline and Alexandra Cousteau, sci-fi author Bruce Sterling, and scientists from NASA and SETI.

More details about the festival can be found on the Smithsonian magazine website.
