What is this movie!

[Paul E. Tick]

My fellow associate and I have been talking about movies this morning, and she mentioned a movie where there was a bunch of Dead people pretty much stacked making a tree. I'm the local movie buff, and I can distinctly remember the visual, but can't think of the movie for the life of me!
