Grant Show appears as Jake Hanson and Daphne Zuniga appears as Jo Reynolds, as their characters from Melrose Place (1992), which is a spin-off from the series.
The show's genesis came from the success that came from having a direct spinoff from BEVERLY HILLS, 90210 to MELROSE PLACE (the Jake Hanson character appeared in several episodes as a love interest for Kelly Taylor, then was part of the MP pilot). Producers on MP used Linda Gray's Hilary character as the estranged mother of Amanda Woodward, then similarly centered a new series around her that Fox greenlit.
