Several times during the movie is mentioned Electra did a lesbian sex scene where she makes love with herself. When people ask her about how this was done, she eludes the question. Later it is revealed Elektra has a twin sister, Celia and they both appear on screen at the same time when Elektra visits Celia in jail and they are identical (apart from hair, make-up and clothes, obviously) so at this point the viewer can deduce the aforementioned sex scene was played by Elektra and her sister.In the final credits, Celia is credited as played by Taryn Gugino, leading the viewer to believe Carla Gugino has a twin sister but this is false. Celia was really played by Carla Gugino herself and she doesn't have any twin sister.
