So I just saw the Martian and there was this preview that really stuck out to me.
The movie was titled "Room" and to sum up what I remember (I have horrible memory but refuse to say its short term memory loss) it's about this mother and her child (son I think) and the child thinks that there is no other world outside of this one room. It's where they've lived their entire life. And I also remember some time during the end of the preview the mom yelling "Don't take away my daughter!" Or something like that even though the child is (somewhat) clearly shown as a boy in about the middle of the preview.
Hopefully my mom takes me to see it, it's rated R but only for language.
