Turning Sue Dearbon into a cat burglar is a major departure from DC Comics canon.
In the comics, Ralph meets Sue after crashing her debutante ball under the pretext of chasing jewelry thieves.
To be sure, Dreyfuss was very surprised when she found out about the twist.

I have like a cool jacket?
And we built a suit and it was so cool to get to wear the catsuit.

They want her to be more than Ralphs love interest, which is really cool, said Dreyfuss.
Making Sue a cat burglar also allowed Dreyfuss to use a skill from her childhood.
And they were like, Really?
And I was like, Yeah, I can see it, I can do it.
Theres a lot to who Sue [is], shes got a lot of layers.
So we had this really like easy chemistry because wed been friends for 10 years, she said.
The biggest thing was just like the comfort level of messing with him.
So it was really fun.
