Dolores first appears serving a few barflies at a bar, with Eddie Valiant being one of them. She notices when Eddie loses his composure after one of the barflies makes fun of him, believing he works for Toons. She apparently cares for Eddie and even helps him when the latter explains about Judge Doom and the Toon Patrol, who are all after Roger Rabbit because he supposedly murdered Marvin Acme. She also seems to know about his will. She plays a larger part in the film's climax, where she saves Eddie from almost being killed by Judge Doom and the Toon Patrol. She is last seen walking beside Eddie as they, along with Roger and Jessica, enter Toontown together while accompanied by all the other toons in the film.
