Which Prue Is It, Anyway? - S1-E16
Continuity mistake: While Phoebe explains the slam man training system Piper puts on Phoebe's boxing gloves, and when Prue says that demons don't play fair Piper playfully raises her left arm to Prue's forehead, but in the next shot facing Prue it's Piper's right arm that's raised. (00:04:00)
Which Prue Is It, Anyway? - S1-E16
Continuity mistake: When Prue goes up to cast the spell, Piper and Phoebe are downstairs and Piper's hair is down. When they hear the effects of the spell they run in to the attic and both say "Oh my god!" one after the other and Piper's hair is now slicked back in a ponytail.
Continuity mistake: In this episode, the sisters go back in time to late March 1975. On the family tree it says that Piper was born on August 7, 1973. So she would be 1 and 1/2 in March 1975. But she looks at least 2 years too old. (00:09:30)
When Bad Warlocks Go Good - S1-E18
Continuity mistake: Prue finds Brendan, as a warlock, over the corpse of Father Austin. He runs away and she pursues him. He insists that he "didn't hurt Father Austin. [He] found him like that." Prue counters, "Before or after you turned into a warlock?" His response is, "After. When I saw what [my brothers] did to him, I was crazed. The rage turned me into a warlock." So doesn't that mean that he found Father Austin before he turned into a warlock, not after? (00:17:55)
Suggested correction: He said after because Brendan has always been a warlock. He was born that way.
When Bad Warlocks Go Good - S1-E18

Suddenly the trees and dead leaves are gone and she is standing in an open area with green grass and no trees.
Continuity mistake: While Andy and Darryl are at the station talking about why Andy's been "walking around...like a zombie," Andy places a pencil behind his ear, but when it cuts to Inspector Blakely walking in behind Andy the pencil has vanished between shots, but it reappears again in the next shot. Then when Andy borrows the photograph of the knife, once again the pencil vanishes between the closeup and wideshot. (00:09:10)
