Attention “Doctor Who” fans: the TARDIS is landing in Denver.

It’s been 50 years since “Doctor Who,” the sci-fi series about a time-traveling humanoid alien and his sentient spaceship, the TARDIS, made its debut on BBC. In honor of that anniversary, the Sixth Doctor, British actor Colin Baker, is joining the list of stars at this year’s Denver Comic Con.

“Doctor Who” ran on BBC1 from 1963-89, and was relaunched in 2005 with Christopher Eccleston as the Ninth Doctor. Baker played the show’s title character from 1984-86, portraying him as a curious and brilliant man with an absolutely bizarre fashion sense.

Appearing with Baker will be Daphne Ashbrook, who played the first companion of the Eighth Doctor, Dr. Grace Holloway. “Star Trek: Deep Space Nine” fans will also recognize her as Melora from an episode of the same name.

Comic book creators Josh Adams, J.K. Woodward and Ben Templesmith, who all have worked on the “Doctor Who” comic series throughout their careers, will be part of the special anniversary programming as well.

The 2013 Denver Comic Con runs from May 31-June 2 at the Denver Convention Center. Convention proceeds will go toward literacy and the arts in area schools via nonprofit Comic Book Classroom. For tickets and more information, go to denvercomiccon.com.
