How well do you think the movie lined up with actual events?
Well, its hard to say based on Wikipedia. Some of his real life they did not cover was his father's suicide in 1995. I think that might have added a bit more drama to the plot, but maybe that would have been too dark considering his heroic play in the water landing of flight 1493. I think over time when people forget or younger generations come to see the movie the effect of the water landing will be that much greater.
The director does cover the wife's worry about the possible drop in his pension. Ironically, even though he was a hero his pay was only 40% of his pre-crash salary despite saving 155 passengers. Luckily, I think the books he wrote afterwards led to having his earnings increase rather than decrease.
I'm sure if they shot it in chronological order there would be much less drama from the crash to the investigation. Eastwood did a nice job of starting in the middle and then have callbacks to the event as well as his earlier life as a pilot. One of the events they cover well is his PTSD following the event as he was reliving the event and possible disaster instead of survival in the crash.
Was there enough material for a film?
I won't know for certain since I have not yet ready Captain Sullenburger's book "Highest Duty: My Search for What Really Matters" based on the true life event. There was a great cover of his learning to fly back in Denison, Texas as a kid and his military pilot career from 1969 to 1979?
At age 12, he qualified for Mensa International, so his IQ was at least 130 while the average joe is at 100. Probably, this was very key in his keen flying ability to be able to think under pressure and land the flight 1493 in the Hudson River.
Overall, I would say its a very gratifying film since we know the pilot from the real life event below.
Do you have any artwork related to Sully?
I don't have any tied specifically to this event, but I do like to cover some of my heros. One of enduring bravery is of Malala, the girl that survived a Pakistani Taliban attack for helping her father bring forth education for girls in a conservative culture impeding it.
