The rehabilitation facility where LaRoche catches up with Jane to conduct his interview is the same one used (for exterior shots) in Bio-Dome (1996). it is the Japanese garden at The Donald C. Tillman Water Reclamation Plant in Van Nuys, CA.
Red-haired actresses: Sarah Adina, Angela Gots, Megan Gallagher.
