Continuity mistake: When Electra is kneeling next to her father's body he's lying on a bunch of papers from the "New York Post" truck, but they look like regular paper, not newspaper type paper. (01:03:26)
Continuity mistake: Close to the end of the scene where Elektra is practicing in her room with the sandbags, she throws a sai into the sandbag with Daredevils face painted on it. The camera then switches to behind her looking down the length of the room, showing the same sandbag without a sai in it.
Continuity mistake: When Daredevil and Elektra are fighting, Elektra is wearing her charm necklace in the beginning of the fight, but after stabbing DD, she is not.
Suggested correction: In the film it is shown that her necklace drops to the ground (chain break most likely) when DD manages to grab Elektra in a choke hold. This occurs about 30 seconds before she stabs him.
Continuity mistake: When Daredevil comes home you see stairs with a wall on the right, from Daredevil's point of view, then in the next shot he's gone down one step and there's no wall on his right, it's now on his left with his dad's gloves on it.
Continuity mistake: In the scene following the death of Elektra's dad, we see Matt hitting all of his weapons and helmets to the ground. As he is he knocking down all his 'numchucks' you notice that one in the center stays on the hook. He puts his back to the wall and begins to slide down. If you look to the left of the screen the last weapon has disappeared. (01:01:50)
Continuity mistake: When Elektra is standing over her dead father her good luck charm is hanging around her neck. In the next shot it is tucked away in her dress. (01:00:55)
Continuity mistake: In the scene where Matt Murdock's father is killed in the alley, Matt is wearing his father's robe and hood. As Matt runs towards his father's body the robe falls off and lands behind him. Matt kneels down, without turning, to hold his father, then when the camera pulls back the robe and hood have somehow moved several yards in front of them. (00:16:05 - 00:17:00)
Continuity mistake: After Electra stabs Matt with her sai, she is bent down to him, with the front of her hair raked back over her ears. When she stands up in the very next shot, her hair changes to being straightened out.
Continuity mistake: Young Matt is in the hospital. His dad walks into the room and you see a respirator machine and an IV bottle on the window side of the bed. His dad sits down on the same side. You now see the machines on the other side of the bed behind him. Matt comes over and hugs his dad, machines still behind them on the door side of the bed. The camera backs out of the door and the machines have moved to the window side of the bed again. (00:10:05 - 00:10:40)
