According to IMDb, Joyce will appear in a 2014 comedy called "MegaBall$." This will be her first acting credit in 14 years.

I remember this being mentioned, one of the people in charge of the production is a relative of Art Carney's. They became close through a recent documentary he is producing about Art and he got her to do a small part in his upcoming film.

Hope she does more movies.
