Intervention, Rockville’s Sci-Fi / Fantasy Convention announces major expansion to its programming and guests for its 7th year


Intervention: The Intersection of Sci-Fi, Fantasy, and Future Media in Rockville, Maryland is proud to announce a major expansion for its 7th year bringing you a “Dragon Con-style” Sci-Fi and Fantasy experience to the Mid-Atlantic area, but in a smaller, easy to navigate size.

Guests include Arthur Darvill (Doctor Who’s Rory Williams, Legends of Tomorrow’s Rip Hunter), René Auberjonois (Star Trek: DS9’s Odo), Juliet Landau (Buffy’s Drusilla), Thomas Dolby (Professor, Composer, Musician), Gigi Edgley (Farscape’s Chiana), Dwight Schultz (The A-Team’s Howling Mad Murdock, Star Trek’s Lt. Barclay), Todd Haberkorn (Hetalia, Fairy Tail, Star Trek Continues), Robert Axlerod (Power Rangers’ Lord Zedd), Jon St. John (Duke Nukem), David Gerrold (Writer, Star Trek: TOS), and many more actors, authors, filmmakers, webcomics and beyond.

Our programming reflects modern and classic Sci–Fi and Fantasy such as Farscape, Star Trek, Anime, the DC Comics TV Universe, and more multi-genre geekery. This draft grid can be viewed on our website (
Autograph and Photo Ops will be available all weekend with the celebrity guests in what will be a rare opportunity to meet the guests in a low stress atmosphere and have real conversations. Only 1200 tickets for the con will be sold.

2016 will also see the launch of “Creator Spaces,” a set of half-table spaces offered at no charge where creators can take turns displaying and selling their goods. Intervention also prides itself on being a friendly, welcoming space for fans of all ages and backgrounds. Its harassment policy has served as a basis for many other cons’ policies. It also has a dedicated children’s programming track for families to share.

Intervention 7 takes place September 16-18, 2016 at the Hilton Washington DC/Rockville in Rockville, MD. Full weekend tickets are available at the pre-registration rate of $60 until Sept. 2nd 2016. Daily tickets also go on sale Sept. 2nd, 2016. Full Weekend Tickets at the door are $65. For more information about the event or to register, visit
