Birds of Prey Season 1 Episode 1

Sherilyn Fenn was originally chosen to play the part of Harley Quinn.

A scene was cut with Barbara working out while she's paralyzed.

Barbara and Wade are breaking up after a six month relationship because Barbara is afraid he is getting too close to learning her secret identity. In the aired version, they meet and start dating.

In this version, when Helena returns from meeting Reese, she and Barbara argue for a good few minutes about who they are, wearing masks, and about Batman.

Background music in most parts belongs to Batman Beyond: Return Of The Joker

When Dinah is exploring the docks, and asks Barbara "you've been here before", the sound effects of animals is from the computer game EverQuest. Hang around in most outdoor zones long enough (try the Commons, or Qeynos Hills) - you'll hear it.

The scene between young Dinah and her foster mother is extended, unlike the aired version, this one has them talking more.

Unlike most series, the unaired pilot became available online to download, which enabled fans to see what the show was like before it aired.

The opening in this pilot does not feature a narration by Alfred, but a news report on television. The scene of Barbara taking a shower is extended and Barbara reaches for the phone to call Helena and she runs to the door fast, other than opening it slow like in the aired version.

The unaired pilot featured Sherilyn Fenn as Dr. Harleen Quinzel, but because she was not going to be able to do more appearances, the role had to be recast.
