The first episode of the Harley Quinn animated series may have only just aired on E4, but fans are desperate to know which stars have put their voices to the various DC characters seen in the show.

It’s been a big year for Harley Quinn fans.

First, we got a whole feature film about the crown princess of crime, Harley Quinn: Birds of Prey and now we have an entire animated series!

Following a failed yacht robbery, Harley finds herself incarcerated in Arkham Asylum, but instead of her boyfriend (the Joker) busting her out, its her best friend (Poison Ivy) that masterminds the jailbreak.

After another incident between Batman and the Joker, Harley realises that he doesn’t love her the same way she loves him. After a quick costume change, she dumps the Joker and is out to make a name for herself.

A brilliant first episode left fans asking why do so many of the characters have recognisable voices.
