Batman Forever is a 1995 American superhero film based on the DC Comics character Batman by Bob Kane and Bill Finger. It is the third installment of the Batman film series, acting as a standalone sequel to Batman Returns. Directed by Joel Schumacher and produced by Tim Burton and Peter MacGregor-Scott, it stars Val Kilmer as Bruce Wayne / Batman, replacing Michael Keaton, alongside Tommy Lee Jones, Jim Carrey, Nicole Kidman, and Chris O'Donnell. The film follows Batman as he attempts to prevent Two-Face (Jones) and the Riddler (Carrey) from uncovering his secret identity and extracting information from the minds of Gotham City's residents, while at the same time navigating his feelings for psychologist Dr. Chase Meridian (Kidman) and adopting orphaned acrobat Dick Grayson (O'Donnell)—who becomes his partner and best friend, Robin.

Schumacher mostly eschewed the dark, dystopian atmosphere of Burton's films by drawing inspiration from the Batman comic books of the Dick Sprang era, as well as the 1960s television series. After Keaton chose not to reprise his role, William Baldwin and Ethan Hawke were considered as a replacement, before Kilmer joined the cast.

Batman Forever was released on June 16, 1995, to mixed reviews from critics, who praised the visuals, action sequences, and soundtrack, but criticized the screenplay and tonal departure from the previous two films. The film was a box office success, grossing over $336 million worldwide and becoming the sixth-highest-grossing film of 1995. It was followed by Batman & Robin in 1997, with Schumacher returning as the director, O'Donnell returning as Robin, and George Clooney replacing Kilmer as Batman.

In Gotham City, Batman defuses a hostage situation orchestrated by the criminal Two-Face, formerly district attorney Harvey Dent, who escapes. Flashbacks reveal that Batman failed to prevent Dent's disfigurement with acid by mobster Sal Maroni, causing Dent to develop a split personality, make decisions based on the flip of a coin, and swear vengeance against Batman.

Edward Nygma, an eccentric and egotistical researcher at Wayne Enterprises, approaches his employer, Bruce Wayne, to present an invention that can beam television signals directly into the brain, demanding immediate approval directly from Bruce. Bruce rejects the device as he is concerned that the technology could manipulate minds. After killing his abusive supervisor and staging it as a suicide, Nygma resigns and plots revenge against Bruce, sending him riddles. Criminal psychologist Chase Meridian diagnoses Nygma as psychotic.

Bruce attends a circus with Chase. Two-Face hijacks the event and threatens to detonate a bomb unless Batman reveals his identity. Dick Grayson, the youngest member of the Flying Graysons family of acrobats, manages to throw the bomb into a river, but Two-Face kills his family in the process. Bruce invites the now-orphaned Dick to live at Wayne Manor as his ward, where he discovers that Bruce is Batman. Seeking to avenge the death of his family, Dick demands to join Batman in crime-fighting, hoping to kill Two-Face, but Bruce declines in order to help Dick move on instead, as he is considering retirement.

Nygma becomes the Riddler and teams up with Two-Face. They commit a series of robberies to finance Nygma's new company and mass-produce his brainwave device dubbed the Box, which steals information from minds and transfers it to Nygma's, increasing his intelligence but also slowly causing him to lose his grip on reality. At a party hosted by Nygma, Batman pursues Two-Face and is almost killed until Dick saves him.

Batman visits Chase, who explains that she has fallen in love with Bruce, and Bruce reveals his secret identity to her. Having discovered Bruce's secret through the Box, on Halloween night, Two-Face and the Riddler destroy the Batcave, shoot Bruce, and abduct Chase. As Bruce recovers, he and his butler, Alfred Pennyworth, deduce that Nygma is the Riddler, while Chase is held prisoner in the Riddler's lair. Bruce finally accepts Dick as his best friend and partner, Robin.
