The filmmakers behind Suicide Squad had someone else in mind before ultimately selecting Margot Robbie to play the beloved character Harley Quinn from the DC comic book supervillain team. Joining an ensemble cast led by Will Smith and Jared Leto, Margot Robbie's portrayal of Harley Quinn received widespread acclaim and has become one of the standout characters in the DC Universe.

Interestingly, it was Emma Roberts who was initially considered for the role of Harley Quinn, but she declined the opportunity in order to star in Fox's satirical horror series, Scream Queens. Despite not being the first choice, Robbie truly made the role her own and brought an iconic energy to the character.

Margot Robbie's portrayal of Harley Quinn spanned three films, including 2016's Suicide Squad, the 2020 spin-off Birds of Prey, and the 2021 soft reboot The Suicide Squad. However, the actress had expressed her desire to take a break from playing Harley Quinn, citing exhaustion from continuous filming. She mentioned in an interview that she didn't know when she would next reprise the role and that she was just as intrigued as everyone else.

While Suicide Squad received criticism for various aspects of the film, such as its plot, dialogue, and direction, Margot Robbie's performance as Harley Quinn was well-received.

The movie still managed to earn $746 million worldwide, despite negative reviews.

Although Robbie initially desired a break from the role, she later expressed a willingness to return to portray Harley Quinn. Nevertheless, her future in the DC Universe remains uncertain.

In conclusion, Margot Robbie's portrayal of Harley Quinn in Suicide Squad and subsequent films garnered immense praise, despite not being the filmmakers' original choice for the role. Her performance brought the character to life and solidified her as one of the standout characters in the DC Universe.
