Factual error: When we see the burning 'DD' in Joe Pantoliano's glasses it is not a reflection. The DD should be backwards in his glasses.

Continuity: Near the beginning of the movie we see that Matt has many visible scars on his back. But when Matt Murdock and Elektra are having sex in the bed there's a shot of Matt turning over onto his back, and almost all of the scars are gone.

Continuity: In the funeral scene, Elektra is exposed to the rain for a few moments, so that Matt can 'see' her face. She then covers up with an umbrella. When she gets in her car, her hair and face are completely dry.

Continuity: When Daredevil kicks Bullseye off his motorcycle, Bullseye has nothing in his hands when he's flying through the air, but when he lands he's holding Daredevil's baton. Watch closely when Daredevil's kick connects, and you can see they never even come close enough for Bullseye to grab the baton, or for him to snatch it if it was dropped.

Other: In the fight scene between Daredevil and Elektra, some of the sheets hanging to dry still have crease lines from taking them out of the package, meaning they have never been on a bed or ever laundered before, just bought for the movie and immediately hung up.

Continuity: When Daredevil throws his stick and it hits Bullseye on the forehead you can see a red mark where it hit, but the next time we see Bullseye he has no mark.

Continuity: In the scene in the subway you see a clock counting down to the next train, at about 01:55. When we cut to the other end of the station though (instantly, because Daredevil's still coming down the stairs), the timer reads 01:35.

Factual error: When Matt Murdock is looking at Elecktra in the rain, he can make out the irises and pupils. This wouldn't be possible for two reasons. Irises and pupils have no depth that could be sensed through his radar sense. Even if they did, he could only see them if the rain was falling straight into her eyes, which would be quite painful and highly unromantic.

Factual error: In the scene where Elektra's father is killed, she picks up what appears to be a Glock 19 and empties it in the direction of Ben Affleck. We hear the weapon click a few times indicating it is out of bullets, but the slide is still in the closed forward position, and it should be locked back when it goes empty.

Revealing: Why is there a full moon every night?
