Heather Langenkamp who guest stars in this episode also guest starred in a previous season as Marie Lubbock, a character whose father Coach Lubbock (Mike's coach and teacher) was spun off in the short lived series "Just the Ten Of Us".
When Mike and Amy leave Barcelona by bus, they arrive in Sitges, a small city about 35 km SouthWest of Barcelona. The establishing shot shows a bus marked "SITGES" in front of the XVII century parish church of Sant Bartomeu i Santa Tecla. The scenes in which Mike and Amy themselves appear were shot in and around Avalon, Catalina Island, California. (The iconic Casino, built in 1929 on the North point of Avalon Bay, can be seen in the background in several shots.)
