Examines the father-son bond during WW2. Can faith move a mountain?

Rating: Null/10 (4 September 2015)

When I told my wife we had the DVD of "Little Boy" from the public library she asked, "Wasn't that the name of one of the bombs dropped on Japan?" I said yes but this movie is not about that. Well, maybe it is.
Set in the 1940s California, in a fictional coastal village called O'Hare, Michael Rapaport is the dad, James Busbee, and he has a very close relationship with his young son, Jakob Salvati as Pepper Flynt Busbee. He is small for his age and the local kids are mean, they usually call him "Midget" but after the local physician suggests it, he takes on the name "Little Boy".
After Pearl Harbor there is a rush for young men to sign up and fight for the USA. The older son, maybe 18 or 19, has flat feet so is rejected and dad signs up in his place. Staying at home is the good mom, Emily Watson as Emma Busbee.
There is also a side story of acceptance, as a local Japanese man, an American citizen who had been there over 40 years, is hassled by the local men because he is Japanese.
This is a "faith" story, the young actor is actually the son of a Minister. Some viewers who adamantly detest faith-based movies will object to this one. But it is a very nice story of a young buy having faith that he can get God to help him get his dad back alive and well from the war.
My wife and I enjoyed the movie, very worthwhile.
SPOILER: The boy talks to the Parish Priest who gives him an old card that lists the works of mercy, feed the hungry, clothe the naked, etc. and tells him many believe doing these works will answer his prayers. Little Boy goes about finding ways to do those things. He gets picked at a magic show and told to make a bottle move. He glares and grunts, hands extended, and the bottle moves. Of course it is a trick but Little Boy has faith. He learns the story of the mustard seed, and on a dare he tries to move a mountain just outside town. The ground begins to shake, is it a coincidence, an earthquake that would have happened anyway? Or did his faith move the mountain? Then the Japanese man shows him on a map where Japan is, tells him at sunset (5:15PM) it is across the water where the sun sets. So Little Boy extends his hands and hopes to free his dad. Newspaper headlines the next day show that Little Boy (the bomb) was dropped on Japan, the war was about over. Was it faith or coincidence? His dad, first thought to have been killed, does come home and seems will recover.
