One of them was, but her scene in the first Suicide Squad episode was kept in. She was also voiced by Arlene Sorkin's nominal replacement as Harley's voice, Tara Strong .
I think her Harley looks great, and she seems to get the characters mannerisms and attitude down to pat. Her voice is a lot more subdued than I was expecting, especially for a Harley voice, but I think she's got the accent down .
