Jonathan Del Arco (Hugh) auditioned for the part of Wesley Crusher at the beginning of Star Trek: The Next Generation (1987).
In an early draft, Lt. Reginald Barclay (Dwight Schultz) took the place of Ensign Taitt. The change was made due to availability and cost issues.
Jonathan Del Arco reprises his role as Hugh from the fifth season's I Borg (1992); however, he shares no screen time with Geordi, with whom he had the closest relationship in the earlier episode, although their friendship is mentioned.
The Borg building (the Brandeis-Bardin Institute in real life) was also used as Camp Khitomer in Star Trek VI: The Undiscovered Country (1991).
