Factual error: When Tina and Jason are in the basement, she sprays gasoline at him. It's clear like water. Considering it's covered in cobwebs, it's been there a long time and would be dark in color, because it gets darker as it ages.
Factual error: In cooking class, the teacher said "two stalks of celery" and Michael handed Lorna one stalk, which she started to separate. One "stalk" is actually the entire bunch (or head), which is made up of 8-10+ "ribs" connected at the bottom. Two ribs will equal about one chopped cup - about right for the tuna walnut casserole made with one can of tuna. Americans typically use the word "stalk" interchangeably with "rib", calling a single rib/ stick/ branch a stalk, but the stalk is the entire bunch. (00:37:02)
Factual error: The film was wholly filmed in Morocco, where the scenery, architecture and geography is wholly different to Israel. All the extras are also Moroccans, who look wholly different and wear different clothing to people from Israel (and would have looked equally different in the first century AD). Many extras were members of the Berber community. Berbers have a long tradition of being tattooed, so many extras showed prominent tattoos. But Jews have a traditional aversion to being tattooed, as per Leviticus 19:28.
Factual error: The closing credits give thanks to "FAO Schwartz", misspelling the name of the famous toy store with an extra "T".
