Sarah Rose Karr is best known to audiences as the adorable young actress who brought heart and humor to the beloved family film Beethoven and its sequel. Born on November 13, 1988, in Los Angeles, California, Karr began her acting career at a very young age, quickly making a name for herself as a talented child performer. She landed her most iconic role as Emily Newton, the youngest daughter of the Newton family, in the 1992 comedy Beethoven, which starred Charles Grodin and Bonnie Hunt. Her portrayal of the sweet and inquisitive Emily, who forms a special bond with the massive St. Bernard, endeared her to audiences and helped make the film a major box office success.

Karr reprised her role as Emily in the 1993 sequel, Beethoven's 2nd, where the Newton family once again found themselves in chaotic adventures with their beloved dog.

After a promising start in the entertainment industry, Karr chose to step away from acting. Her final credited role was in the 1996 television movie The Summer of Ben Tyler, which starred James Woods and Elizabeth McGovern. Following her departure from Hollywood, Karr largely retreated from the public eye, prioritizing a private life away from the spotlight.
