Notice actress Melissa Sue Anderson's make-up job as she sits in a near catatonic state in bed at Nellie's Hotel. She's wearing lots of orange-ish rouge, pink lip gloss and quite a bit of frosted blue eye shadow--definitely more 1980's than 1880's. Besides being over-the-top and out of place, Mary would have looked much more unkempt if she had really been sitting in bed for days on end. Furthermore, her curls are perfectly coiffed in many of those scenes. It makes sense that her mother and sisters helped brush her hair every day, but are we expected to believe that they washed and curled it too?
