The Telephone (1988)

Synopsis
In this comedy-drama, Vashti Blue (Whoopi Goldberg) is a struggling actor who takes out her frustrations via the telephone, in various accentual impersonations, by making prank calls from her apartment. Off the screen Goldberg attempted to prevent the release of this version of Telephone by filing suit, but apparently did not win the case. Many critics seem to insist she was right in doing so. ~ Kristie Hassen, All Movie Guide
