In The Texas Chain Saw Massacre (1974), Gunnar Hansen could run faster than Marilyn, so he had to do random things when chasing her through the woods (you will notice in one head-on shot that he starts slicing up tree branches in the background).
Found dead by family members at her Houston, Texas home on August 5, 2014.
Received her Bachelor's degree in Drama from the University of Texas at Austin (1971).
Had written, directed, produced and performed in several plays for children. She also directed and worked on theatre plays in Houston, Texas until her death.
Aside from her roles in horror movies and occasional appearances at horror conventions, Marilyn lived a relatively quiet life out of the spotlight in the Houston, Texas area during her later years.
