For all the Star Trek fans,. Today I learned that the actress that play Nurse Ratched in "One Flew over the Cuckoo's Nest" was the same actress that played a religous Bajorian zealot in some episodes of "Depp Space Nine". The part was very similarly played for her to be a birch. I always thought she looked familiar and this while watching "deep Space Nine" I saw the name in the opening credits so looked it up.
Edit: It seems she won the Oscar for Best Actress for "One Flew Over the Cuckoo's Nest".
