Other mistake: During the dinner party scene, Carl is going gopher hunting. The shot of him approaching the tree shows it's daylight in the background, when the previous shot showed it very very dark out.
Other mistake: There is a man and a woman who do the voices on the radios Leon listens to at Game Control. The man also does the voice for 530 AM at the airport, while the woman does the voice for the airport intercom, first noticeable when the White Team arrives at the airport. The woman then does the voice of the hotel operator, "Paging Mr. Player." These two are very busy indeed.
Other mistake: When Clark and Lois are on their way to the diner, the wide shot of their car driving along looked very familiar. In fact, it was footage used in the first movie, where the car was used as part of Lex Luthor's "real-estate" plan and was run on remote control. If you look closely in part II, no one is driving the car yet you hear Clark say to Lois, "Hey, you seem pretty quiet over there...."
Other mistake: The scenes with Flash and Aura in the shuttle are a complete mess. She tells him that the left lever controls direction, the right controls the altitude. When they are passing the planet Aquarius, she tells him to take a left turn over Fridgia. A) They are passing Aquarius at the time, not Fridgia. B) He moves the right lever instead of the left lever. C) The craft doesn't change direction or altitude and even if it had moved left as supposed to, they would have ended up crashing into Aquarius. The scene when Flash wants to talk to Dale is even worse. He pulls down the left lever to dive into Fridgia. It is the wrong lever. Then when he pulls back up, he correctly uses his right hand, but the right lever is already in the up position as seen in the previous shot. (00:42:15)
Other mistake: At the end of basic training, Judy's platoon goes to the bulletin board to see what their M.O.S. will be. This is not how the U.S. Army operates, you must pass a qualification test for the M.O.S. that you enlist for before you ever enlist. You know before you ever get to basic training what M.O.S. you will be training for, not on the last day of basic training.
Other mistake: When Kit Mambo prepares to catch up with Renè Fromage, she first overtakes two guys (the raccoon and the bighorn sheep) on 'third and fourth positions' - as announced by Barbara Warbler, then she passes the sheep and the camel before she catches up with Renè. This would place her first competitors on positions five and four, instead of three and four.
Other mistake: When Arthur's father takes his ball away (just before Richard Collier signs the register), Richard is looking the other way while Arthur's father puts the ball somewhere behind the counter. Yet, when Richard decides to give Arthur his ball back, he reaches over the counter to the exact place Arthur's father placed it even though Richard never saw where it was placed. (00:54:30 - 00:57:10)
Other mistake: Cpt. Yelland and civilian observer Lasky are trying hard not to mess up with the timeline. Changing little things in the past could have tremendous results in the present/future. However they already disrupted the natural timeline by shooting down 2 Japanese Zeros, killing both pilots, leaving behind CAG Owens in 1941 and rescueing secretary Laurel Scott who would've been killed for sure by the two previously shot down Mitsubishi Zeros.
Other mistake: When Jack Nicholson is talking to the manager of the Overlook Hotel, the manager mentions the death of two girls aged 8 and 10. When Danny sees visions of the two girls they are unmistakably twins, not different ages. A quick look at the IMDb (http://uk.imdb.com/title/tt0081505/fullcredits) proves they are - Lisa and Louise Burns, both born in 1968.
Other mistake: After the state troopers collide with Bob's pickup truck, both vehicles crash into a fire hydrant improbably located alongside a deserted country highway. (01:29:45)
Other mistake: Rosa and her co-worker couldn't possibly be watching Terrible Tommy as she and Princess War Star enter the arena as the movie starts. Because later on they're shown wrestling in that same arena wearing those same outfits wrestling, a sign that scene was shot at a different time or a part of the wrestling scene where Rosa and another wrestler are watching Tommy.
