Revealing mistake: When the Angels are fighting the "Creepy Thin Man," right before Drew Barrymore lifts up Lucy Liu to spin her around and kick the thin man, to get Lucy's attention, Drew hollers out "Lucy!" even though Lucy Liu's character's name is "Alex." (00:26:20 - 00:27:25)
Revealing mistake: In the swimming pool scene, when David is sitting at the bottom of the pool, you can clearly see a scab on one of his knees. (00:43:00)
Revealing mistake: When the leading hitman jumps from the balcony you see him land on a rubber mat.
Revealing mistake: When Austin enters the bathroom at the casino, keep your eyes on the door during the scene - it opens by itself before closing. (00:31:10)
Revealing mistake: In one shot when the boat is pulling away from the waterfall, you can clearly see that the shot is the same one they used earlier in the movie. The water from the waterfall now is going up the cliff! They have just put it in reverse.
Revealing mistake: During the bedroom scene with Felicity and Fat Bastard you can clearly see the air hose that fills his suit when he rolls over in the bed. (00:49:10)
Revealing mistake: When Lara Croft goes into the water near the end to try to save her male rival, Alex West, after he is stabbed and ground between the gears, when Lara stands up, you can see the make-up coming off her arm that covers Angelina Jolie's "Billy Bob" tattoo.
Revealing mistake: When Anna and Hans are dancing in front of the lighthouse, we don't see the shadow of the railing or the ground they're standing on.
Revealing mistake: When Luke is being fed to the Rancor, in Jabba the Hutt's dungeon, there are black outlines around the beast's legs, from the composite's blue screen special effect. This was edited out in the special edition rerelease.
Suggested correction: This was not a "mistake". The outlines showing around the beast's leg were due to the limited CGI technology at the time the film was made. With advances in special effects in the following decades, the filmmakers were able to enhance the CGI quality in later releases.
But it is a mistake to show that the Rancor is not real, and the outlines show that. It's certainly not intentional.
Not sure what you mean that the rancor is not real. Of course it's not real. The issue is, at that time, it was not technically possible to show the beastie without the lines showing. I classify a mistake as something that was not intentional. In this case, it was, due to the limitations of CGI in the 1980s.
Revealing mistake: At the beginning of the scene near the end of the movie with Lucius Malfoy fuming at Dumbledore in his office, Malfoy's hair is fanned back behind his shoulders. The lighting in the room illuminates the back of his neck, where you can see his real, short brown hair. (02:22:05)
Revealing mistake: While Poe leads the aerial assault on the oscillator, in the closeups of Poe and other X-wing fighter pilots, note the cockpit windows at the pilots' left and right have identical marks and scratches in their individual X-wings. It's particularly noticeable when one closeup follows another.
Revealing mistake: When Joe Dirt gets lifted up by another man and thrown to the ground you can see that Joe is a stunt double.
Revealing mistake: When the High Priestess gets hit by Ikol's Shuriken star the guiding wire for the projectile is visible.
Revealing mistake: When Amidala and Anakin are eating and he cuts her a piece of the fruit and "floats" it back to her, the bite appears in the fruit a split second before she actually eats it. [This appears to be fixed in rereleased versions]. (00:53:40)
Revealing mistake: While Indy and Marion are in the Well of Souls, and they encounter the snakes, Indy falls to the ground only to be confronted by a hissing Cobra rearing its head. Look carefully and you'll see the snake's reflection on the safety glass between it and Indy. Briefly you can also see the torch's reflection while he's waving it around. You can also see Marion's reflection when she falls in later on and is face to face with the cobra. [This has been corrected in the new DVD set. You can only see it if you have the original VHS. I think it's visible in the "making of" on the DVD as well.]
Revealing mistake: In the freeway chase scene when one of the agents jumps onto the hood of the first car then jumps off, the car flips, then a second later as the car is still flipping you can see the gas tank and transmission have been removed. (01:23:45)
Revealing mistake: When Will Scarlet finds the injured Much in Sherwood Forest about three quarters of the way through the movie, a white vehicle can be seen travelling from right to left in the background. (01:27:40)
Suggested correction: No car, just light on the hilt of Scarlett's sword.
I verified the scene. It's definitely not from the light of Scarlett's sword. It occurs after Will gets off his horse and the horse is turning. To the right of the horse is a tree in the background. To the right of that is a small clearing, about level with the horse's mouth. For a fraction of a second you can see a white object go across the small clearing in the same manner as a white car driving by.
Revealing mistake: After the helicopter escape at the end, a red sports car is sticking nose-down in the ground after falling hundreds of feet down out of the aeroplane, without a single crack in the windscreen, in mint condition. The yellow one only has the right door open. (01:59:30)
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: In the catacombs of the library, Indy and Elsa are waist deep in petroleum. Indy has a torch, and if you look carefully, you will see burning pieces of the torch fall and hit the petroleum. Wouldn't this start a fire as Kazim later on sets the cavern alight with a single match? (00:34:05)
