Visible crew/equipment: Just as Jack says, "On deck, you scabrous dogs," to the very left edge of the screen over Jack's shoulder is a grip crew member with a tan cowboy hat, white short sleeve tee shirt and sunglasses, just standing there looking out to sea.
Continuity mistake: In the bridge fight scene where Colossus and Negasonic Teenage Warhead appear, Deadpool tries to escape Colossus' handcuffs by severing his hand. The hand that he cuts off is his left, but when he jumps off the bridge the severed arm is on his right side.
Other mistake: When the stormtroopers break into the control room, the stormtrooper on the right of the screen hits his head on the door frame. On the DVD release they've added a thump when he hits it.
Other mistake: When Iron Man and Iron Monger are fighting, Iron Man catches the SUV, and you can see the family inside the car. Although the car is completely vertical, the hair of the people in the car seem to defy gravity.
Continuity mistake: In the scene near the end where Ajax has a knife in the side of Deadpool's head and is punching him, later Deadpool pulls the knife out. In a follow up shot there is no hole in the mask where the knife was, but in a later shot the hole is there.
Continuity mistake: When the ferry starts splitting in two, there are people standing at the back and cars on the bottom. In a wide shot the people and cars have disappeared, then the people reappear a few seconds later, as do the cars in a later shot.
Continuity mistake: In the library scene Indy discovers the "X" high up on the balcony. The X is green with a grey background. But when he breaks the tile to find the tomb the X has disappeared and the ground is a solid green.
Trivia: You just have to see this to believe it. When Roy and Johnny walk into Brackett's office with him, to listen to the tape of 110's rescue, as soon as they stand around the desk, while Brackett is talking, Johnny puts his hand around a golden smallish object on Brackett's desk, pulls it close to him, palms the item and very quickly stashes it in his klepto pocket. Randolph Mantooth pulled off a beauty here without breaking character, and the director actually left the prank in instead of a retake. So enjoyable to watch.
Other mistake: When Anna's horse gets scared and runs off, Anna falls into a stream and gets soaked. Trouble is, everything else in the kingdom is frozen solid - the sea, waterfalls, etc. - there's no way that stream would still be liquid.
Revealing mistake: Once the secret door to Moria is open, when Gimli says, "Soon Master Elf, you will enjoy the fabled hospitality of the Dwarves," as Gandalf leads the way inside, note the glint of the trailing power cord as it moves along the ground behind Gandalf and goes directly under his robe. This is the staff's electrical supply cable.
Corrected entry: When Dana is tested if she's telling the truth, right after she says "Who would make up story like that?", we can see her saying "yeah I know" silently, as if she had messed up that line.
New this monthCorrection:She says "make up a story like that". She didn't mess up the line. Why she made the facial expression is therefore moot.
Other mistake: In the end of the title sequence, Jessie walks outside. Before exiting, you can see that she is just a little bit taller than the doorway, but her head passes through the frame as she walks forwards.
Other mistake: When Harry spits baby food on the baby (the camera lens in actuality) in retaliation for the baby spitting food on him and Tommy, Joseph Gordon-Levitt breaks character and laughs uncontrollably and looks at and gestures to off-screen crew members a couple times.
Continuity mistake: When the hobbits are hiding under the tree trunk from the Ringwraith in the beginning, you can see space to the left and right of the tree above them. Logically when the Ringwraith walks past the tree you would see it on the right side of the tree first, then on the left, but you don't - it looks like it walks out of the tree instead of behind it. [Confirmed on the commentaries - Elijah Wood asks his fellow actors if anyone spotted the mistake: 'It kind of magically comes out of the tree'. Sean Astin: 'You mean it doesn't pass from the other side?' Wood: 'No, it comes out from the centre.']
Visible crew/equipment: In the opening scene, a velociraptor is being introduced into the park from a shipping container. The velociraptor runs into the gate as it opens, knocking Jophery off the top; he falls to the ground and is attacked. As he falls, two hands come in to break his fall and prevent him from hitting the camera or hurting himself.
