Rain Man.

Barry Levinson's 1988 film "Rain Man" unfolds the compelling story of a self-centered Los Angeles car dealer, Charlie Babbitt (played by Tom Cruise), who discovers that his estranged brother, Raymond (Dustin Hoffman), an autistic savant with an extraordinary memory, has inherited the vast majority of their father's estate. Set against the backdrop of a cross-country journey from Cincinnati, Ohio, to Los Angeles—a trip that revisits their past in Ohio—the film masterfully explores themes of love, understanding, and acceptance. Raymond's connection to Cincinnati, Ohio, not only grounds the narrative in a tangible place of origin but also adds depth to the brothers' rediscovery of family ties. "Rain Man" stands as a cinematic landmark, combining profound character development with a heartfelt portrayal of autism, ultimately achieving universal acclaim and shedding light on the unique gifts and challenges faced by those on the autism spectrum.
