Then the truck pulls back and you get a rear shot of the car and again the bumper is fine. Its only after the finally hit does it really show the bumper as being messed up in all scenes after that.

Before the big battle at the begining of the film, the Romans are preparing to fight. They show the enemy across the field where they have just moved into position and are also preparing  to fight.

In the next shot, looking at Dad over Indy's shoulder, the cup still has water in it and Connery takes another sip.

At the ending of the movie, Steven Seagal is fighting a group of terrorists in a grocery store.

"Another 48 Hours"
In the movie, Eddie Murphy and Nick Nolte sit in the back of a police car talking to a man. When they're all finished up, each of them opens the rear doors and exits the vehicle. Wouldn't real criminals love to be in the back of a squad car that had door handles on the inside?

"Miss Congeniality"
In the movie, Sandra Bullock and Miss Rhode Island are in a club eating pizza with some of the other pageant contestants. Everybody else goes back to do this paint drum thing and Sandra Bullock and Miss Rhode Island stay to eat pizza.

"Judge Dredd"
The blooper is best seen on a big screen TV or you just might miss it. Anyway, Max Von Sydow is talking about Sylvester Stallone at a podium when they have a massive close up of him. The shot is just perfect enough that you can see, believe it or not, several boogers up his nose!!!! I about died because as he talked and breathed, the vile mucous flaps back and forth, in plain sight!!!! I don't know what the director was thinking! Maybe he was trying to show that people from the future get congested too. Who knows. But I think it's one the grosser, unbelievable bloopers in history.

"Ocean's 11"
While Brad Pitt and Matt Damon are talking, just before Julia Roberts is introduced into the movie, Pitt is, in one frame, holding a glass, with something like shrimp, with a towel flopped over his arm. In the next one, the glass is changed into a plate he's eating off of.

"First Knight"
Here's a simple one, but one that I notice every time I watch the movie, and seemingly forget that I saw it before since I exclaim my subtle annoyance at it every time. In the movie "First Knight" with Richard Gere, Sean Connery, and Julia Ormond, at the final climax scene, just after Richard Gere vanquishes the evil Prince Malagant, his sword is broken. It is nothing but the handle and the hilt. This happens after stabbing him, and cutting his throat twice. There being no reason for the sword to break for one, and for two, it is then handed back to King Arthur (It was his sword, so sup- posedly Excalibur I would imagine) while he is on his deathbed. Had the camera been positioned half an inch higher, it would have been concealed.

"Born on the Fourth of July"
The front yard is cluttered with junk, including a white chair swing hanging from one chain, when Ron Kovic (Tom Cruise) visits the family of a man he accidentally killed in Vietnam. But while he is in the house, someone must have slipped out and fixed the swing because it's hanging from both chains when he gets back into the cab to leave.
