Continuity mistake: Maureen spent the first night in the spooky house, without conclusive results. They are meeting the prospect buyers in a bar. When Lara walks up to them and begins the conversation, the arm position of the man changes wildly between shots several times at every cut. (00:08:40)
Continuity mistake: Mikey dropped the wristwatch Andrew gave him and it landed face down with the bands upward. When Mikey jumped off the rock to retrieve it, the watch's face was on its side (visible to the screen) and the bands were parallel to the ground. (00:05:04)

Continuity mistake: Mike and Tommy at the beginning of the movie are in the desert and have been staring at nothing for 3 months and 6 days. When Mike says this precise amount of time, and earlier when he asks "What's your point, Tommy?" the lid of his scope flaps in the wind. In the rest of the scene it stays still. (00:02:20)
Continuity mistake: Michelle Rodriguez goes back and forth using the character of Frank's voice to using her own natural voice.
Continuity mistake: The gang Bo is reluctantly part of gets to Maurice's crib where he is playing cards with his homies. The red jacketed one is defiant, and grabs a handful of red and blue chips in front of him tossing them in Angelo's face. But if you check out of the table in the wide shots before this occurs, you'll notice that red chips were never in the stack in front of him to begin with. (00:19:05)
Continuity mistake: John Biswas is tailing the little deaf girl. His scooter breaks down and he follows her on foot. They are walking in the same road in two different shots, with a cut just a few meters apart. The toys in her right hand and the paper in her left swap hands in the second shot. (00:18:20)
Continuity mistake: The main character is chatting with Harper at the shooting range. Harper's earbuds and protective goggles change position between shots throughout the scene. (00:08:50)

Continuity mistake: The chef at the airport stabs someone, but the knife blade is clean afterwards; moments later he stabs it through the valise, and it is covered in blood.
Continuity mistake: Throughout the movie, fire axes seem to be the weapons of choice. Only two fire axes are used, but they appear recurrently. In the very first use, the protagonists grab fire axes to butcher the monster called Beverly. Blood and gore go everywhere; yet, the axes emerge from this bloodbath with no blood or gore on the handles - they're virtually pristine moments later. The axes are used again and again, right up to the ending, and blood comes and goes from the axe handles seemingly at random.
