As Brantley runs from the dog after leaving the pool house, the close-up of him climbing the trellis shows that it is broken. Distance shots show the trellis intact.
When Brantley comes into the takeover meeting at the end of the film, he walks down the side of the boardroom table toward Davenport and his left collar is tucked inside his sweater while the right collar is outside the sweater. Shortly after speaking to Davenport the left collar is shown out. In subsequent shots the collar is in on some shots out on others.
While Brantley is watching out of the window in his uncle's company, we see that someone is walking through the hallway towards him. In the next sequence from another angle, we expect the person to pass Brantley, but there's no one there and nowhere for them to go even if they were.
