Plot
In 1947, cartoon characters, commonly called "toons", are living beings who act out cartoons in the same way that human actors make live-action production. Toons interact freely with humans and live in Toontown, an area near Hollywood, California. R. K. Maroon is the human owner of Maroon Cartoon studios; Roger Rabbit is a fun-loving toon rabbit, one of Maroon's stars; Roger's wife Jessica Rabbit is a gorgeous toon woman; and Baby Herman is Roger's costar, a 50-year-old toon who looks like an infant. Marvin Acme is the practical joke-loving owner of Toontown and the Acme Corporation.
　
Maroon hires private detective Eddie Valiant to investigate rumors that Jessica is having an extramarital affair. Eddie and his brother Teddy used to be friends of the toon community, but Eddie has hated them, and has been drinking heavily, since Teddy was killed by a toon a few years earlier. When Eddie shows Roger photographs of Jessica "cheating" on him by playing patty-cake with Acme, Roger becomes distraught and runs away. This makes him the prime suspect when Acme is found murdered the next day. At the crime scene, Eddie meets Judge Doom and his Toon Patrol of weasel henchmen. Although toons are impervious to physical abuse, Doom has discovered that they can be killed by submerging them in a mixture of solvents he refers to as "Dip."
　
Baby Herman insists that Acme's will, which is missing, bequeaths Toontown to the toons. If the will is not found by midnight, Toontown will be sold to Cloverleaf Industries, which recently bought the Pacific Electric system of trolley cars. One of Eddie's photos shows the will in Acme's pocket, proving Baby Herman's claim. After Roger shows up at his office professing his innocence, Eddie investigates the case with help from his girlfriend Dolores while hiding Roger from the Toon Patrol. Jessica tells Eddie that Maroon blackmailed her into compromising Acme, and Eddie learns that Maroon is selling his studio to Cloverleaf. Maroon explains to Eddie that Cloverleaf will not buy his studio unless they can also buy Acme's gag-making factory. His plan was to use the photos to blackmail Acme into selling. Before he can say more, he is killed by an unseen assassin and Eddie sees Jessica fleeing the scene. Thinking that she is the killer, Eddie pursues her into Toontown. When he finds her, she explains that Doom killed Maroon and Acme in an attempt to take over Toontown.
　
Eddie, Jessica, and Roger are captured by Doom and his weasels and held at the Acme Factory, where Doom reveals his plan. Since he owns Cloverleaf and Acme's will has yet to turn up, he will take control of Toontown and destroy it with a mobile Dip-sprayer to make room for a freeway, then force people to use it by dismantling the trolley fleet and make a fortune through a series of businesses built to appeal to the motorists. With Roger and Jessica tied up, Eddie performs a vaudeville act that makes all but one of the weasels literally die of laughter (the leader is subjected to the Dip) and confronts Doom. Doom survives being run over by a steamroller, revealing that he himself is a toon and admitting that he killed Teddy. Eddie eventually dissolves Doom in the Dip by opening the drain on the Dip machine. As toons and the police arrive, Eddie discovers that an apparently blank piece of paper on which Roger wrote a love poem to Jessica is actually Acme's will, written in disappearing/reappearing ink. Eddie kisses Roger—proving that he has regained his sense of humor—and the toons celebrate their victory.
　
Critical reception
Who Framed Roger Rabbit was also a critical success and received positive reviews. Roger Ebert gave a positive review, predicting it would carry "the type of word of mouth that money can't buy. This movie is not only great entertainment but a breakthrough in craftsmanship." Janet Maslin of The New York Times commented that "although this isn't the first time that cartoon characters have shared the screen with live actors, it's the first time they've done it on their own terms and make it look real". Desson Thomson of The Washington Post considered Roger Rabbit to be "a definitive collaboration of pure talent. Zemeckis had Walt Disney Pictures' enthusiastic backing, producer Steven Spielberg's pull, Warner Bros.'s blessing, Canadian animator Richard Williams' ink and paint, Mel Blanc's voice, Jeffrey Price's and Peter S. Seaman's witty, frenetic screenplay, George Lucas' Industrial Light & Magic, and Bob Hoskins' comical performance as the burliest, shaggiest private eye."
　
In contrast, Richard Corliss, writing for Time, gave a mixed review. "The opening cartoon works just fine, but too fine. The opening scene upstages the movie that emerges from it," he said. Corliss was mainly annoyed by the homages to the Golden Age of American animation. Animation legend Chuck Jones made a rather scathing attack on the film in his book Chuck Jones Conversations. Among his complaints, Jones accused Robert Zemeckis of robbing Richard Williams of any creative input and ruining the piano duel that both he and Williams storyboarded.
　
As of October 2011, 46 reviews collected by review aggregator Rotten Tomatoes indicated 98% of reviewers enjoyed the film, earning an average score of 8.3/10. The consensus reads: "Who Framed Roger Rabbit is an innovative and entertaining film that features a groundbreaking mix of live action and animation, with a touching and original story to boot." Metacritic calculated an average score of 83, based on 15 reviews.
