Amy Smart has a short nude scene in movie Mirrors. She takes off her clothes and takes a bath and we get to see a great shot of Amy naked from behind.
Paula Patton is also in the movie but she doesn’t have any nude scene in it. Best chance of seeing Paula Patton nude is in movies Deja Vu or Idlewild. Paula also appeared nude on the CD cover of her husband’s, Robin Thicke's, A Beautiful World cd (thanks to Chans for submitting this cover).
