10 Actors Who Were In The Orville AND Star Trek

6. Robert Picardo

The second of Star Trek's doctors on this list, though the first to appear in The Orville, Robert Picardo donned the Xelayan forehead, nose, and ears to portal Ildis Kitan, chief of security Alara Kitan's father.

Picardo is no stranger to appearing in multiple Sci-Fi properties, with appearances in Stargate SG-1 and Stargate Atlantis to his name as well. He first appears in the season one episode of The Orville, Firestorm, on a monitor, discussing Alara's fear of fire - and her underperformance academically, in his eyes.

Picardo returned in Home, appearing alongside John Billingsley and Molly Hagan, who plays Drenala Kitan, making the episode a Trek reunion of sorts. Picardo's Ildis is Billingsley's Borrin's primary target, as the latter blames him for the suicide of his son.

Ildis represents the struggle between academia and the military, if not in conflict, then in terms of perception. For Ildis, Alara's 'slower' mind was a source of shame, as was her decision to join the military. He finally comes around when she demonstrates her skill in saving her family.
