Character mistake: The archbishop wears a red zucco on his head at the dinner. Purple is the color of a bishop or archbishop. Red is the color of a cardinal.
Suggested correction: Generally true, but the specifics are not straightforward. The problem lies in the interpretation of "purple." Depending on the source, the purple may actually be "amaranth red" (which is a reddish-purple, but may look more like fuschia) or "magenta" (which may appear to be a reddish-purple or a purplish-red). Magenta is an equal mixture of red and blue, so the result should look somewhere between red and purple. How these colors or blends are perceived on screen may vary with the tint setting.
Also, it may be possible that the more reddish-looking zuccetto was meant to be and match the choir's red.
Character mistake: At the funeral the Greek mayor makes the sign of the cross in the Roman Catholic way, not the Orthodox way. His hand should have gone from the right to left side of the body.
Character mistake: When Jerry and Scotty are talking in Scotty's bedroom, after his Mom's kidnapping, there is a poster behind Scotty's door. The poster says "Accordian King" but should have been spelled, "Accordion King."
Character mistake: When Greg and Rose are playing backgammon, Rose counts the middle of the board as a place to count when moving a piece, but the middle of the board isn't a place to count.
Character mistake: At the boat when the two bodyguards frisk Shag, he fakes a gay yelp and then walks away with Erin. You can see the one guard on the right, try not to break (crack up) as they walk away.
Character mistake: The final scene in which the Hatches leave the overpass that they take shelter under in the final tornado has the family walking off as the sun has risen. Jack states in his narration that the tornadoes occurred over the span of three hours, thus creating an incorrect timeline as the events leading up to the tornadoes hitting Blainsworth take place in the evening; the Grand Island outbreak does take place over three hours, however all seven tornadoes touch down between 8:45 and 10:45 p.m.
