The film cited is about 90 minutes in length.  Did not watch it.  Frida was a Mexican national.  Married to Diego Rivera, both painters.  Rivera was older and married at the  time he took up with Frida. Frida also had relationships with women such as Josphine Baker.  Rivera had an affair with Frida's younger sister.  
So the basic telenovela of the times.  Guessing the film dealt with the painting and the angst of her life.
