It’s a big moment in any movie when one of the main characters dies, whether in battle, by accident, foul play, or natural causes. The nice people at the information site ChaCha have done the math and figured out which actors have died most often in movies. They also point out some interesting patterns and coincidences — De Niro was killed by Pacino in “Heat” and then Pacino was then killed by De Niro in “Righteous Kill” and Bruce Willis had two movie deaths at the hand of his then-wife, Demi Moore.
