When Robin Simmons (played by Rachel Wilson) was serving Brussel sprouts, she used a towel to remove the casserole from the oven. Immediately after, she used her bare hands to remove the glass lid which would have been very hot. She again picked up the casserole with her hands to serve the sprouts in the dinner plates.
The characters of Jessica and Evan are only engaged, yet they have the same last name, Crowder. (This, however, is not necessarily an error, perhaps they chose to have the same surname for convenience. This is the 21st Century after all.)
When the burglar leaves Jessica and Evan's apartment, he heads in the direction away from the apartment's exterior door.
At the end of the movie, when Jessica brings Simon the book she wrote, it is clearly a hard cover book with a dust jacket. When he picks it up, it is a soft back copy.
When Simon is in his bedtime attire, one can see that he has a tattoo which would be atypical for the "early 1960s gentleman" to which he aspires.
