During the scene in the motel room, Jamie's wedding band switches hands and disappears several times.

When Henry's father is recreating Mary Shaw's body, Billy the doll is clean in one shot but dirty and broken in the next.

(at around 55 mins) When Detective Lipton confronts Jamie at his father's house, the perspiration on the left side of the Detective's face alternates between dry and wet between shots.

When Lisa is attacked by the Doll and is spitting blood out on the floor, the white sheet on her back keeps moving from being wrapped down around her waist, to pulled back up almost to her shoulders between shots.

After Lisa puts the white sheet over Billy the Doll, it constantly changes position in the way it is draped on the bed.

Jamie pronounces his wife Lisa's name as 'Leesurr.'

When Detective Lipton confronts Jamie in the hotel room after Jamie tries to bury the doll, there are several occasions when Lipton's mouth does not match the words being spoken between cuts or isn't moving at all.

Jamie states that in his hometown, receiving a ventriloquist dummy out of nowhere is a bad omen. If so then why didn't he get rid of it when it arrived at his doorstep?

The ventriloquist dummy is considered evidence due to the fact that it arrived the same day Lisa died, yet the doll is not retrieved from the crime scene allowing Jamie to take it to his hometown to investigate its history. Det. Lipton confronts Jamie for trying to get rid of evidence by burying the doll which could have easily been avoided if the authorities had simply retrieved the doll from the crime scene.

Jamie is considered a suspect in Lisa's death as he was the last person to see her before she died. However, he was off buying Chinese food as she was being murdered and by the time he got back, she was already dead. He could have simply shown the receipt with the time printed on it as evidence that he wasn't home when it happened, or the authorities could have simply visited the takeout place and seen the surveillance footage, but this never occurs to any of the characters.

The trunk that Billy the Puppet arrived in was from Jamie's hometown of Raven's Fair. It took Jamie less than 10 seconds to figure this out himself. Why didn't the authorities retrieve this trunk themselves as evidence along with the doll from the crime scene? If Jamie is a suspect in Lisa's death, then they'd want to take it to prove that Jamie mailed it to himself.

Lisa was murdered through ripping her tongue out. There is no reason why a ventriloquist puppet would be considered evidence of any kind, as it can't be a tool for such a murder.

When Detective Lipton interrogates Jamie on the death of Lisa, actor Ryan Kwanten accidentally flubs his line and says her name as Liser.
