At the beginning of the movie, Annabelle tells Sam she's a vegetarian. On one of their dates when she cooks him dinner, she says they are having chicken pot pie with couscous.
When Sam offers to take Annabelle out for Italian food in celebration of her grand opening, Annabelle says she is off gluten, but then proceeds to eat sambusas, which are classic fried savory pastry, made with gluten, during their "international" meal/celebration.
When Annabelle and Sam are on their first date, they stroll outside along some storefronts and their breath is visible, even though they are dressed for a warm evening. Near where they stop to look in a storefront display, was a small leafy green tree and some flowers. These were clearly props, as it was past the time of year for green leaves and blooming flowers.
Annabelle and Sam have to move their wedding ceremony to an inside location from the planned outside golf course because of the downpour. Scenes of the wedding ceremony show through the windows of the building that it is bright and sunny outside.
