Factual error: That is not a crocodile that attacks Sue. It more closely resembles an American alligator - the squat, rounded snout gives it away. Australian crocodiles have a much sharper, more angular snout. There are other tell-tale physical features, most notably the placement of the alligator's teeth when it closes its mouth, but that's the main one.
Continuity mistake: When Moana is throwing sticks into the ground, after she starts singing, look back at that spot and all the thrown sticks have disappeared.
Revealing mistake: When the boys drive the car over the gap in the bridge, look at the side view that shows the main jump, watch the front wheels, they lift up in the air unnaturally before the car leaves the ramp. (00:34:00)
Revealing mistake: The kid in the wheelchair is playing a Game Gear with no game in it.
Continuity mistake: When Dr. Dolittle is giving CPR to the bear, the bear is completely dry. If you just rescued something from the water, it should be wet. (00:35:30)
Continuity mistake: When Marty chases after Biff on the borrowed 'skateboard', Marty is wearing a dark grey belt and a red/blue print shirt under his red/beige jacket. However, when Marty is hanging on to the front of Biff's car as they turn a corner (and in another shot), Marty (stunt double) is wearing a light brown belt and solid tan shirt. (01:07:00)
Character mistake: When Missy is at her audition, Courtney and Whitney get annoyed and tell her to do a sequence, (front handspring stepout, roundoff back handspring stepout, roundoff back handspring, full twisting layout). However, when Missy starts the sequence, she starts with a cartwheel instead of a front handspring.
Factual error: The story is set in 1976. "Funkytown" is used in the movie and the end titles. The song was not released until 1980.
Continuity mistake: When Toad General calls for the council's attention and announces that Bowser found the Super Star, note his shirt buttons. Then, when he says that the Kongs will never agree because their mad king doesn't make alliances, Toad General's shirt is backwards, his buttons are on the opposite side. (00:24:55 - 00:25:35)
Continuity mistake: The morning after Vivian's first night at the hotel, room service brings breakfast. When she's eating a croissant it cuts to a shot of Edward, and when it cuts back to Vivian she's eating a pancake which goes from being half done, to being a whole pancake again. (00:30:55)
Revealing mistake: When Han shoots at Bruce Willis and the others with the Gatling gun, we see cartridges on the ground. You can tell that they are all blanks. The tip is jagged and has been closed - live ammo just has an open hole where the bullet was.
Other mistake: Near the start of the movie Jon indicates that he has titanium in his right arm, but towards the end of the movie the bullet ricochets off his left arm. (00:08:55 - 01:34:45)
Continuity mistake: When the WABAC machine is going through the time vortex, trying to escape from the black hole, some tiles get sucked off the WABAC, but in the next shot they are back on.
Factual error: The movie takes place during the 1990s, but throughout the movie cars are shown with Illinois license plates with "Illinois" written in cursive. These plates were not introduced until 2001. (00:24:45)
Continuity mistake: After defeating Fulton Balcus, Sean removes the armor and has no clothes on. As Sean and Mizky leave, Sean is wearing sneakers. Mizky only brought him a shirt to wear.
Revealing mistake: When Claude and Ray are at the retirement home getting ready for bed, as Ray lifts up his shirt you will see where it looks like he's wearing a fat suit underneath. He can also be seen pulling it down to his waist.
Visible crew/equipment: Near the end, when Rodmilla and her daughters are requested to appear before King Francis, in the first shot facing the king and queen, there is a beige narrow mat in front of the large patterned rug, which is not in previous or following shots, specifically used for crew/camera tracking (fullscreen version). (01:50:30)
Factual error: When the B-52 is flying low over Russia, the shadow on the ground is a Boeing B-17G, a World War II propeller driven bomber.
Continuity mistake: In the scene where John is peeing off Stifler's balcony, he knocks over a plant and knocks out Christy. In the next shot the plant is back, and in the one after that it is gone again. (00:17:15)
Revealing mistake: Gracie hugs the Russian waitress in order to have a better view of the disc hand-off appear on the monitor. As she raises her left hand that holds the book/camera lens, we see that the digital feed that appears on the monitor stays steady and level, even though she is raising the book/camera lens higher and closer to her face. Obviously the feed that we see on the monitor is not taken from the book/camera lens. (00:04:10)
Suggested correction: You can tell by the shape of the snout and the ridges above the eyes that, although animatronic, it is meant to be a Marine Crocodile that is native to Australia. It doesn't resemble an American alligator, which doesn't possess those pronounced ridges. Also, freshwater crocodiles can be seen in the boat ride scene where Mick motions for Sue to lean up off the edge of the boat. They have the narrower, angular snout that you referenced.
The placement of the alligator's teeth when it closes its mouth shows that it is more like an alligator than a crocodile. In fact, the animatronic puppet is a bizarre mish-mash of physical characteristics of both crocodiles and alligators.
