 Matt Groening , the creator of The Simpsons , felt that Jessica Lovejoy was hard to draw in his own style but at the same time make her attractive . Julie Kavner , who provides the voice of Marge Simpson on the show , was particularly impressed by the eyes . Jessica was made the Reverend 's daughter to give the impression that she was good at first and then to show that she was rebelling against the righteousness of her family . In the scene where Bart talks to Jessica outside her house , her baton playing was in the script but the exact choreography was not . Dietter liked its incorporation because it gave Jessica something else , other than Bart , to pay attention to . This was also done in the final scene when Jessica scrubs the church steps and plays with the scrub brush .
