I know this is a very late reply, but you need to understand that the one essential, indisposible element needed in dramatic storytelling is CONFLICT.
No one wants to go and watch a movie about a loving couple who are there for each other at all times, with no bumps or ruffles and are supported by their perfectly understanding and patient parents. Bor-ING.
This movie isn't a documentary. As for finding 'truths' from an official website, I for one am wary of that also. I didn't know the man, and sadly never will.
Never defend crap with "It's just a movie"

Sadly, most movies that are made to portray someones life, or a series of real events are like this. Remember the Titans, American Gangster to name a few are pretty inaccurate. Most people would like to see the real story, but the movie execs would rather see the money that comes with making these movies a little more interesting.
