The Other Sister is a 1999 American romantic comedy-drama film directed by Garry Marshall and stars Juliette Lewis, Giovanni Ribisi, Diane Keaton and Tom Skerritt.

[3] After receiving a well-earned certification from a sheltered boarding school, Carla Tate, an ambitious young woman with a mild intellectual disability, returns home to her overprotective and slightly snobby mother Elizabeth.

Envying Danny's freedom, Carla convinces her parents she is capable of living on her own and moves into her own apartment.

Danny gets drunk, then seeks solace and insight (and a joyride in a vintage Ford Mustang convertible) from his landlord and friend, Ernie.

During a Christmas party at the country club, nervous about his personal lot, Danny drinks too much to build up his courage to declare his love for Carla.

At her older sister Caroline's wedding, Danny surprises Carla by showing up at the church and asks her to marry him, in a scene mimicking The Graduate, the couple's favorite film, to which she accepts.

Carla angrily tells her mother that she is sick of her combination of three behaviors: dominance, negativity and doubt.

Outside the church, Danny surprises Carla with their school's marching band playing "76 Trombones" from The Music Man, and they are chauffeured away to their honeymoon in Ernie's prized Mustang.

"[11] Lewis was nominated for a Golden Raspberry Award for Worst Supporting Actress for her performance, where she lost to Denise Richards for The World Is Not Enough.
