I think you're rightif it were a real poem, we could "google" it and it would be theresomewhere.

They say something like:
"And on her footfall,
In rustle of leaves,
Her whisper on the wind,
She speaks from a place beyond mortal pain".
I think it is a fictitious poem, because I couldn't find about it too. If anyone else wants to try

I agree. In the scene where someone says a line or two of the poem, one of the friends asks "remember, Rachael in Heaven?" It's like they knew it from somewhere. Like you said, it might have been in school. But they never say any more of itjust those two lines. I was able to write down a bit "on her foot fallshe speaks from a place" and that's all I was able to write down. And that's not all of what they said of it. I should have had paper and pencil close by. I'd just like to read the entire poemif it is a real poem. You never knowit might be.

I'm also trying to find the poem referenced. I think "Rachael in Heaven" must have been a nickname for a poem they had to memorize or study in school.
"I'm with the Government and I'm here to help you."

Almost 8 years after your post, here I am also looking for something about the poem. I tried "google" but the only thing I got was a poem written for a young woman who was killed in England. Could that be it? I don't know But the next time I see the movie, I'm going to try to write down exactly what they say and see if those words are in the poem I found. Have you had any luck?
