Noel Neill was cast as Lois Lane in the 1948 Superman serials but the first year of The Adventures of Superman, Phyllis Coates was cast as Lois Lane. Due to difficulty lining up a time slot, by the time they were ready to shoot the second season, Coates was involved with something else. So Noel Neill was hired to reprise her earlier role. Neill had a cameo in the first Superman movie as Lois Lane's mother. Phyllis Coates played Lois' mother in Lois & Clark-The New Adventures of Supereman. Terri Hatcher of Lois & Clark then did a guest shot as Lois' mother in Smallville.
