The movie is David Duchovny`s screen debut. He appears in two scenes; once at Tess`s birthday party at her apartment and later at Cyn`s engagement party. This is also Oliver Platt`s first screen role.
Michelle Pfeiffer and Meryl Streep were considered for the roles of Tess McGill and Katharine Parker respectively. Studio executives seriously considered Shelley Long for the role of Tess McGill because of her high TV Q rating at the time. Lorraine Bracco revealed in her memoir, On the Couch (2007) that she was devastated when director Mike Nichols didn`t offer her the title role after she thought she gave a great audition.
When Tess goes to meet Katharine Parker on the helipad, she is carrying a stuffed gorilla, a direct reference to the film Gorillas in the Mist, a film that Sigourney Weaver had finished a few months earlier. (en.wikipedia.org)
