Mine are,
The Deer Hunter - really shook me up and stayed in my head for a long time.
The Exorcist - watched it in secret with my big sister, it terrified me and I couldn't sleep for weeks.
The Sound of Music - the whole family watched it together every Christmas, so it just makes me feel good.
Good Morning Vietnam - fell in love with Robin Williams.
Thelma and Louise - girl power, and Brad Pitt, enough said.
