Reunion - S2-E10

Revealing mistake: When Angel kicks in Lindsay's door, it opens cleanly into the room. The doorknob latch in a real door would have torn out part of the frame if it was not turned back with the doorknob first. (00:04:25)

Phoenix

That Old Gang Of Mine - S3-E3

Revealing mistake: Supposedly the demon Merl has no tongue, but when he is telling Angel the apology he wants, it can be seen. (00:01:00)

Phoenix

Happy Anniversary - S2-E13

Revealing mistake: When Wesley accidentally turns off the power, the room briefly goes dark, then lights up with moonlight/streetlight from outside. In the real world, that light would have been visible the whole time in the background. (00:01:45)

Phoenix

The Shroud Of Rahmon - S2-E8

Trivia: Cordelia and Wesley realize that the robbery is happening that night because the door latch is taped down - exactly the same way the guards at the Watergate Hotel realized a robbery was in progress in 1974, which led to President's Nixon's resignation. (00:27:20)

Phoenix

War Zone - S1-E20

Revealing mistake: When Alonna is kidnapped, there is a vampire on the left side of the screen who is not wearing any mask over his face, though sunlight is falling on him. (00:26:00)
