6. Winifred Freedman
The character played by Winifred Freedman on “Mr. Belvedere” was not a huge role. She played Wendy, who appeared in only six episodes. Freedman, however, has been in many other projects. Her acting career started in 1982. She made her splash in Happy Days as Annette Mastorelli but has acted consistently since the 80s, mostly in TV. In 2006, she was in “Desperate Housewives,” and in 2008 she was in “Without a Trace.”
