Robert O'Reilly's appearances on the last season of Star Trek: Deep Space Nine marked a decade of work on Star Trek. O'Reilly's introduction to Star Trek: The Next Generation was in the episode entitled "Manhunt" in which he portrayed the gangster "Scarface." He then successfully auditioned for the part of the Machiavellian Klingon leader, Gowron, for the episode, "Reunion."

Besides the many appearances on Star Trek: The Next Generation and Star Trek: Deep Space Nine as Gowron, Robert has participated in many Star Trek related extra-curricular activities including a Decipher VCR Interactive Board game, lithographs sold nationwide on QVC, a sci-fi Fantasy model, three action figures, life-sized, stand-up Gowron poster, and most recently, starring in the CD-ROM "Star Trek: Klingon" for which Robert won the Sci-Fi Universe Reader's Choice Universe Award for Best Achievement in Genre Multi-Media. In this game not only will Robert teach you how to be a Klingon, he also will teach you how to speak like one.

Robert's stage work has spanned a broad spectrum from Shakespeare ("King Lear" and "Hamlet") and Sam Shepard ("True West") to original plays ("When The Bough Breaks") and the original production of "The Grapes of Wrath." He is proud to have starred in the original productions of "The Martian Chronicles" and "Fahrenheit 451" (plays written by and based on the books by Ray Bradbury, who has since become a friend).

Robert directed his play in 1981—Marsha Norman's "Getting Out—and was promptly nominated by the Los Angeles Drama Circle for Best Director of the Year, the most prestigious award given to a Los Angeles theater director. Since then he has won or been nominated for every other major directing award the Los Angeles area has to offer. His original production of "Generations" by Dennis Clontz received National Honors as a runner-up to August Wilson's "Piano Lesson" for the best play produced outside of New York City.

In spite of his busy schedule, Robert continues, each year, to direct one play and act in at least one theater production. He is a member and Artistic Advisor at the Colony Studio Theater Playhouse, a repertory company in Los Angeles that boasts a 90% subscription rate. Recently, he directed the "Mornings At Seven," and acted in "Fool For Love" by Sam Shepard.

Robert has appeared in over 100 films, made-for-TV movies, and television episodes. His most recent projects include the soon-to-be released films "Moonbase," in which he stars as the evil convict Stark, and "Good Luck," starring Gregory Hines. He has also appeared in the "The Mask" starring Jim Carrey, as well as ten other feature films. Mini-series and movie-of-the-week appearances include "Desperado: Badlands Justice," "World War III," "From Here To Eternity" and "By The Dawn's Early Light." Television series include NYPD Blue and two seasons on In the Heat of the Night and Dark Justice. Other episodic television credits include such series as Murder, She Wrote (2 appearances), Dallas (2 appearances), Hunter, Falcon Crest, The Flash, Hill Street Blues, Max Headroom, The Equalizer, Sledgehammer, Paradise, Jake and the Fatman, MacGyver, and many more. Robert generally portrays villains or antagonists and is particularly expert in the use of a variety of dialects and accents.

Robert resides with his wife in Los Angeles. During his infrequent times of rest and recreation, you may find him playing a round of golf, attending an enjoyable game of baseball, or watching a good film or television show, particularly if it's set in the Star Trek universe.

Robert's wife gave birth on January 1, 1997 at 12:01a.m., 12:03a.m., and 12:04a.m. to Jack, Joseph, and Michael—their three sons.

Note: Robert was credited as "Bobby Reilly" in his appearance in "Badda Bing, Badda Bang" (DS9-566).
