Somewhat outdated and sexist term used to describe the primary exclusive assistant to the
star on a movie. While most films have 2 top billed stars only the one at the 'top of the marquee gets. A girl friday. Girl Fridays are often actually guys. Since shooting a picture is so time consuming actors can be on set 16-20 hours per
day to print maybe 3 minutes of finished product.so girl Fridays take care of all ancillary tasks for the
star such as laundry. Any/all correspondence and arranging on set visits with family. On set duties may include but are not limited to such pedestrian tasks as bringing.coffee/lattes and food to the stars trailer limiting access to the
star by basically being a buffer not to be
rude but to protect the
star in question
