Revealing mistake: When Sonny is punching Carlo under the spraying fire hydrant, he misses an audible punch by at least six inches. (01:43:30)

Factual error: When Charles Bronson is making a telephone call on a pay phone, a 1971 or like vintage Mustang is parked within view...out of place for the time the film is supposed to take place. There are other similar auto related mistakes, mixing thirties cars with late models in traffic scenes.

Character mistake: While he may not have figured it out the moment he found the forest dying, certainly a botanist like Freeman Lowell would know plants need light to survive.

Factual error: The Liberty Bell is depicted ringing as the Declaration of Independence is being signed on July 4 (a mistake itself) in the film. The bell actually did not ring on that date, but on July 8, when the Declaration had been returned from the printer and unveiled to the public.

Revealing mistake: At her wake, Rose blinks when Paul leans in to clean her face.

Revealing mistake: Although the film is set during the aftermath of the Mexican War (1848-50), the mountain vistas display some lovely radio towers and fire ranger stations.

Revealing mistake: In a scene where the canoes are shooting the rapids through a sheer cliff you can clearly see a stuntman climbing out of the water onto the rock.

Continuity mistake: Gene Hackman and John Shea are both doused with water when they come out of the restroom. In the next shot, their hair is completely dry.

Visible crew/equipment: Near the end of the chainsaw sequence, a crewmember's hand is visible on Krug's back.

Continuity mistake: The protagonist is weilding his karate skills against the crooked cops in the final fight scene. One of his foes is wearing a white fishing cap. Superfly belts him and knocks of the cap, there is a cut and then the cap is on again. The cap is on and then off again twice more in the same fight scene.

Factual error: When Sally and Bryan are in the street, we can see, at their back, election posters. These posters appeared in 1932, one year after the movie is supposed to take place.

Visible crew/equipment: When Robert and Arvid are in the desert and Robert falls into the pit, you can see the shadow of director Jan Troell holding the camera.

Continuity mistake: After Bruce Lee kills Chuck Norris, he walks back and picks up Chucks Gi and Obi (karate shirt and karate belt). The belt is hanging and dragging on the floor but as Bruce walks from behind a column, the Obi appears to be folded properly.

Continuity mistake: At the end of the film when Oliver Reed is in the Range Rover and ramming the Hillman Avenger, watch the number plate of the Avenger. It switches repeatedly between a 'K' suffix and a 'J'.

Audio problem: When Bruce Lee finishes fighting with the Japanese school using a nunchaku and is going to fight with the fat man, he folds the weapon and tosses it to the floor on his left. It lands without making a sound.

Revealing mistake: When Itto is bathing, near the beginning of the film, he hears the clanking sound and then there is a close-up shot of his face. The start of his wig, the hairline, is visible. (00:08:48)

Revealing mistake: At the beginning, when the woman in the flotation seat is paddling backwards, you can see a fishing line attached to the back of seat that is being pulled to help her move backwards.

Other mistake: It makes no sense that the pimp would die from having the tip of his tongue bitten off. (00:23:35)

Revealing mistake: At one point when the soldiers are walking through the jungle, one of them steps into a trap and is pulled up into the trees to be killed by Indians. However, if you watch this scene carefully, when the soldier (who steps into the trap) walks into frame you can see a wire already attached to his foot leading up into the trees. He doesn't step into a trap. (00:22:26)

Continuity mistake: During the opening credits, Peter Boyle is seen loading luggage into a red Ford convertible with a rear license plate reading 677 EIY. When he parks in front of the Community Legal Services office, the car's front license plate reads 185 ENV. A few moments later, when he goes to meet Robert Redford, the front plate reads 772 DYD.
