Continuity: Jerome rips his jacket sleeve seam while punching out the police officer, yet soon after it is intact.
Crew or equipment visible: As Vincent gets ready for his first day at work as Jerome, he pulls out his shirt from the closet and you can see fingers of someone holding the closet door open.
Continuity: In the scene at the piano recital, there's a bouquet of flowers to the right of the piano (shot from overhead), but when the pianist is finished, and takes a bow, the vase (and flowers) have vanished.
Crew or equipment visible: The dolly track can be seen on the left of the screen when Vincent is standing in line to have a blood test done.
Continuity: When the two men are swimming at night, they are sometimes shown to be naked, and other times (underwater shots) shown to be wearing boxers or swimming trunks.
Crew or equipment visible: When the detective shows the picture of Vincent to the director, the power cable to his "hand-held display" (prop) is clearly visible running around his hand and up his sleeve.
Audio/visual unsynchronized: Because they are occurring some distance away, the numerous rocket launches shown should not be audible until a several seconds after liftoff.
Continuity: When Jerome and Eugene are out at the club, on the table there is smoke coming out of Jerome's wine glass before he blows the smoke into it.
Continuity: In the beginning when Vincent is putting the blood into the fake thumb he puts it on his left thumb but he always uses his right hand to get tested
Continuity: After Irene and Vincent have sex, you can see that the bedroom walls are pure glass (including the corner of the house). You can also see a view of the beach and ocean. Later when Vincent is on the beach scrubbing himself with sand, the house is viewed from the beach. At that point you can see pillars in between pieces of glass on the house, including the corner.
Factual errors: Several of the items used in the film to check DNA (urine, hair and eyelashes) in fact have no DNA. A sample of hair or eyelash will have DNA if the hair follicle is still attached, but the DNA is not actually in the hair--and hair samples often have no follicle attached. Urine may contain a few cells, but they would be few and many more cells can be obtained much more easily.
Factual errors: When Vincent is confessing to Irene, he tells her he doesn't have 20 or 30 years, his heart is already 10,000 beats overdue. In an average male this would only be about 2 1/2 hours, not several years as the story suggests.
