The marriage of O'Brien to Keiko was a result of the desire by writers to portray a shipboard wedding. The producers wanted such a wedding to involve an established character, and even toyed with the idea of Picard becoming permanently married. They decided instead for the marriage to include a more peripheral character, with O'Brien seen as filling such a role. Keiko was created for the episode, and was originally developed as Wesley's replacement in the Conn position.
Wide shots of Data and Dr. Crusher tap dancing featured a dancer double for Data, only. Gates McFadden is an accomplished tap dancer, and did all her own work.
Debut appearance of the character of Keiko Ishikawa-O'Brien played by Rosalind Chao. Keiko would become a semi-regular character on both TNG and Star Trek: Deep Space Nine (1993).
Gates McFadden received double billing in the credits: 1) In the opening credits for her role as Chief Medical Officer Beverly Crusher. 2) In the closing credits as Choreographer.
This was the first appearance of several locations aboard the Enterprise-D including the arboretum, the barbershop, the nursery and the replicating center.
