Director Rich Christiano mentioned "Before we showed this movie in theaters, we first screened it in some Christian film festivals, and the first one we ever showed this movie at was in Boston ..." (at 36:13 in 'Behind the Secrets of Jonathan Sperry'). That was The Merrimack Valley Christian Film Festival in Lawerence, 29 miles north of Boston (3/16/2008-3/23/2008). Rich Christiano also refers to this screening at 25:07 in the DVD commentary, saying the film "wasn't even finished yet."
When Mr. Sperry challenges the boys to form a chain stretching from a tree to a $5 bill he places on a picnic table (at around 1h), shots from behind the boys show half the table in sunlight, while the reverse shots (which had to be shot on a different day) show the table completely in shadows.
At the conclusion of the movie, we see all of the boys listed and the way their futures resulted. What are the actual names of those historical characters?
