From a 1966 article in Radiocorriere we learn that she was born in Naples, where she continued to live when not in Rome for film and TV work and that in addition to her acting studies she was also a student of pianoforte at the Accademia di Santa Cecilia. She looks to have been most active in television and radio (she has numerous radio credits in Radiocorriere) and she was also a singer.
Anna Maria does not appear on the actors list on the Centro Sperimentale di Cinematografia website, though I suppose it is possible she could be listed either under a different name or in a different category, but she does have multiple c.s.c. credits, so I think we can be sure that she did attend and graduate - her being a c.s.c. graduate is also mentioned in the Radiocorriere article.

- Lycanthropus (1961) There is an otherwise unknown Anne Marie Avis credited with c.s.c., listed as playing School girl by IMDb, which seems very probable to be a pseudonym for Anna Maria. I didn't recognise her among the many similar-looking mature schoolgirls, but I think it is very probable I could have missed her.
