The scene in "Dr. T" with baby Eric is of his actual moment of birth.
Robert Altman had made arrangements with several expectant women for
their participation in the filiming. A two-wall minimal set was
prepared at the hospital to be set up when necessary for the birth. The
first two women who were to deliver developed complications requiring a
C-section and could not be filmed. With the third setup, the birth went
normally and baby Eric made his movie debut.
