Continuity: When Robert Deniro shoots the pimp's hand off in the hallway (shortly before shooting Sport the second time), blood splatters on his face, across his left eye and forehead. As he stumbles up the stairs (still shooting the handless pimp), the blood has changed, and finally in the shot where Deniro pantomimes shooting himself, the only blood on his face is on his chin.

Continuity: In the scene at the diner, where Travis puts a soluble tablet in a glass of water, you can see a plate of open cheeseburger in front of him. But Travis never ordered, nor received any cheeseburgers. He only ordered and received a cup of coffee only.

Continuity: While De Niro is talking to Jodie Foster you can see a bus out the window. When the screen switches to Jodie Foster's view you can see the same bus driving, but then it changes back to De Niro's view you see the same bus driving up to the window again. This keeps happening throughout the scene, the bus keeps driving around the building.

Continuity: In the scene where De Niro shoots and kills the man robbing the convenience store, the clerk takes De Niro's gun off of him and starts beating the already dead body with a pole. If you watch the scene carefully, the dead body changes positions contrary to how the man is hitting him. Clearly the scene was shot several times with the dead body being placed in different positions.

Visible crew/equipment: Right before De Niro's character is shot in the neck, you can see the small charge used to detonate the blood.

Other: When Travis sends money to Iris, he addresses the envelope to 240 East 14th st. At the entrance to the building Iris lives in, the address is 224 E. 14th St.

Visible crew/equipment: In the scene right after DeNiro is watching the Senator on the TV, he is driving in his cab past the campaign headquarters. As the camera goes past the window and focuses on desk phone, you can see the reflection of a cameraman for a second or so in the glass.

Revealing: When De Niro gets shot in the neck, his bald skin cap wrinkles considerably when he presses the wound with his hand. Confirmed by make-up artist Dick Smith in the making-of documentary. Submitted by William Bergquist

Visible crew/equipment: In the scene where Robert De Niro shoots Sport the pimp in the stomach, the bullet supposedly goes through Sport's back, and blood splatters onto the doorway framework behind him. However, as Sport falls to the ground, look closely, and you can see a wire dangling from his lower back, which was used by the special effects team to detonate the fake blood packet. (Timecode)

Continuity: During the same scene there is a white van parked across the street behind De Niro. Then it's gone. Then it's back.
