Movie Soundtrack Question

[Stephen]

Whoever can answer this will gain my love forever.




"The Blood of Cu Chulainn" by Mychael Danna. (See Link to hear it)

This song is used in the opening of the film Boondock Saints. But I have heard it somewhere else...and I cannot place it. What films have used this, film, TV, or video games. I know I have heard it in something else. I was so sure it was Braveheart, but I own the soundtrack to that and it was not on it.
