'Star Trek: Discovery' news: Three actors join cast as Starfleet officers; leaked image hints new look for Klingons

Three more characters have joined the upcoming CBS All Access reboot "Star Trek: Discovery."

According to reports, Terry Serpico, Maulik Pancholy, and Sam Vartholomeos have all boarded the show. The three latest additions have been tapped to play Starfleet officers. Serpico will portray a high-ranking Starfleet official named Admiral Anderson. He is known for his roles in "Rescue Me," "Sneaky Pete," and "Army Wives." Pancholy is set to portray Dr. Nambue, who serves as the Starship Shenzhou's chief medical officer. His acting credits include "30 Rock" and "Weeds."

Rounding out the trio is Vartholomeos, who will play Ensign Connor, a junior officer in Starfleet Academy who has been assigned to work in Starship Shenzhou. His most recent notable projects are "The Following" and "The Secret Life of Walter Mitty."

The new additions join the previously announced cast members including Sonequa Martin-Green, Doug Jones, Michelle Yeoh, Anthony Rapp, James Frain, Chris Obi, Shazad Latif, and Mary Chieffo.

Production for the series is underway at Toronto's Pinewood Studios. A new image from the set has been leaked, and it shows what is believed to be Klingons sporting a new look. As noted by Trek Radio, the photo was sent by a source whose friend is currently working on the show's set. The photo's caption leads the media outlet to believe that the person who shot it is actually working in the set as a Klingon himself. The warrior race will reportedly play a major role in the story.

"Star Trek: Discovery" has been in the works for a long time now, and it went through a number of delays. It was initially scheduled to launch in January of this year, but it was then pushed back to May and then to an unspecified future release.

CBS has yet to announce a premiere date for "Star Trek: Discovery."
