Near the end when Wren and Albert are walking to the tombstone, Wren stops and picks some flowers. The flowers are a mixed bunch and the bunch is quite small. In the next shot the flowers are no longer mixed (it is all the same flower) and the size of the bunch is now twice as big.
When Roosevelt accidentally backs the car into the Captain Chicken statue, it leaves a huge dent in the rear end of the car. However, directly after the statue lands on the car and begins to hump it, the dent in the rear end has completely vanished.
Inside Roosevelt's car, the trim around the air conditioning control panel on the dashboard changes from light brown to black between scenes.
Right after Roosevelt backs his Volvo into the Captain Chicken statue, the rear bar on the Volvo's roof rail has vanished.
When the Captain Chicken statue falls on Roosevelt's Volvo, the feather on the statue's pirate hat falls off, and its tail cracks. However, in all subsequent shots, the statue is completely undamaged.
The interior for Roosevelt's car is tan, while the exterior is banana yellow. On 1980s Volvo 240s with yellow exteriors, the interior was only available in dark brown, while the tan interior was available in other colors. Also, the only shade of yellow available on the 1986 Volvo 240 model was cream yellow.
When Wren gets a text message from Aaron, she asks April how he got her number. But his name is clearly displayed at the top of the message so she must have his number stored in her address book.
When the chicken statue falls onto the roof of the car, it continues to move for several minutes despite no longer being connected to anything (most notably, a power source).
At Captain Chicken, the music on the radio cuts off directly after Roosevelt accidentally backs the car into the Captain Chicken statue, even though no one turned off the radio.
When Wren says "What do ya think about these moves, April? How'm I looking now?", her mouth is clearly not speaking the words.
When Roosevelt brings in Wren, April and Peng to meet his mothers, Jackie and Barb, they are playing the Pachelbel Canon as a lute and flute duet. However, Jackie is only heard strumming her lute, because her fingers are clearly not moving.
When Wren and her family arrive home towards the end, it is full daylight yet her mom says it's 5:30 a.m. In Ohio, it's still dark at 5:30 a.m. in November.
