Factual error: All Arabic texts in the film suffer from wrong directional rendering. Arabic is a right-to-left language. Its letters have different joined and disjoined forms. The film, however, has rendered Arabic texts from left to right in disjoined letters. These texts aren't semantically wrong, though. For example, deciphering the Arabic message at 0:40:45 point gives "أليس "التنين فنان؟ Translation: "Isn't the Dragon an artist?" The film has even adopted a good font for them.
Factual error: The crow (mechanical at least in part) perching atop the dead tree lacked some details/behaviors that would've been displayed by a real crow. Its tail should have been thinner and longer (not short and wide, although they do fan). It would have repeatedly cawed upon noticing Geary and Fenn approaching to alert family members of potential danger. It would not have straightened its head to watch the men; the dominant eye would be used to see better (monocular vision is better than binocular). (00:04:40)
Factual error: There was a lot of thunder and lightning before the lightning strike that set the barn on fire, but there was no obvious loud thunder AFTER the strike. Lightning can be seen BEFORE the sound of thunder (because lightning travels faster than sound). (00:03:25)
Factual error: Kurt Warner worked in the Hy-Vee grocery store in 1994. The Wheaties box he took off the shelf featured Dan Marino #13, which was available in 1995. A 1994 Wheaties box featuring the NFL 75th Anniversary Collectors Edition had a different design and color. Unless Kurt also worked in the store into 1995, the Wheaties box he held in the movie was not yet available. (00:39:50)
Factual error: Unless left in the vehicle (not the case here), towed impounded vehicles do not have keys. Moreover, lacking keys, a valid registration, possibly proof of insurance, and new plates, vehicles bought at a NYPD auction are to be TOWED away. A newly-purchased auctioned vehicle, such as the Navigator in the movie, is "ticket-" or "citation-ready", not ready to be driven on the streets.
Factual error: Before Tom landed in the puddle, there was water dripping or it was raining on it, but it wasn't raining when he was on the rooftops. After Tom landed, the water drops/rain suddenly stopped. Even if the water drops were from earlier rain running off the roof or other parts of the building, they would not be hitting the whole way across the puddle or that far away from the edge of the building.

Factual error: No judge would award guardianship of a person with something like autism to a sibling who's a recovering alcoholic and drug dealer.
Suggested correction: I think it is POSSIBLE, but not probable. Someone on the spectrum may have poor coping skills when dealing with strangers or would not do well if placed in an unfamiliar environment. Placement with a sibling - even one as you described (recovering alcoholic and drug dealer) - may be less traumatic and disruptive than with a non-relative or stranger. A judge would have to weigh the bad against the good while considering the person's needs and the sibling's ability to meet or exceed those needs.
Factual error: When Lucy goes to see RKO executive VP Charles Koerner after "The Big Street" was released in 1942, one of the posters on the wall in the waiting room is for "Stromboli", which was not released until 1950.
Factual error: "The Waltons Homecoming" is a remake of the 1971 TV-movie that led to the 1972-81 television series "The Waltons." In one scene, John-Boy has written a story for The Boston Arts Scholarship Competition. He addressed the envelope to "1815 Redwood St, Boston MA 02122." The movie is set in 1933. The Postal Service did not introduce ZIP codes and two-letter state abbreviations until 1963.
