The cab scene where Helen and Jessica talk about blending lipstick was filmed after the filmmakers hailed a cab, paid the driver $20, the director drove, the director of photography was in the front seat and the sound woman climbed in the back trunk.
The film is based on a play called "Lipschtick," the original title of the film was "Seeking Same."
Some background shots were removed from the film prior to its release because they showed the World Trade Center.
Many "extras" in the film were people who just happened to be walking by the cameras during filming in New York City.
