Amy McDougall/Barone (Monica Horan) becomes Robert Barone's second wife (in season 7), and is the best friend of Debra, who introduces her to Robert. A recurring character for the first seven seasons of the series, Amy became essentially a regular cast member for the remainder of the show's run.
Wow, they are really taking casting Lois Lane seriously!!!! Amy Adams is an Oscar Nominee and a serious actress. She practically changes personalities and sometimes looks from role to role. Lois Lane is a hard character to perfect, since the last person who played the part in Superman Returns played it one-dimensional. Kate Bosworth just came off as annoyingly b#tchy.
