These are my favorite picks for movies like Aquamarine. Keep in mind that the list is in no particular order. Enjoy the recommendations.
Jane (Ashley Olsen) and Roxy Ryan (Mary-Kate Olsen) are teenage Long Island twins who find themselves on numerous misadventures when they trek into Manhattan on a school day. While the studious Jane intends to give an important speech in hopes of winning a scholarship, the more relaxed and carefree Roxy wants to track down her favorite New York City rock group. Trailing behind them, however, is Max Lomax (Eugene Levy), their school’s obsessive truant officer.
Princess Rosalinda Maria Montoya Fiore (Demi Lovato) is about to be crowned queen of the small nation of Costa Luna. General Kane (Johnny Ray Rodriguez), the dictator of neighboring country Costa Estrella, invades her palace with his agents during her coronation rehearsal, and attempts to capture the royal family and take over the country. Joe Mason (Tom Verica), an agent of the Princess Protection Program, a secret organization funded by royal families that looks after endangered princesses, whisks her away to safety via helicopter. Kane’s agents, however, succeed in capturing her mother, Queen Sophia.
Abby Jensen (Debby Ryan) has been planning for her sweet sixteen birthday since she was a little girl. On the inside door of her bedroom closet, she keeps a list of secret wishes that she wants to come true. When the big day finally arrives, she excitedly adds her sixteenth and final wish to the list: a photo of Logan (Keenan Tracey) her crush.
Then begins the first of many unusual occurrences, each including visits from a peculiar woman, Celeste (Anna Mae Routledge). She first appears as an exterminator when the Jensen’s house gets overrun by wasps from a nest in their attic that has been building up for 16 years. The Jensen family are unable to go back into their house until the wasps are exterminated, however Celeste manages to extract Abby’s wish list from the house.
Casey Carlyle (Michelle Trachtenberg), a very smart and talented science student who lives with her mother Joan, plans to pursue a scholarship to Harvard University. For the scholarship, Casey must present a personal summer project about physics. While watching a figure skating competition with her mathematically inclined friend Ann, Casey realizes that her favorite childhood hobby, ice skating, would make a perfect project. She decides to try to improve her own skating by applying physics and what she has discovered from watching other skaters.
At the behest of her new stepfather, Joe (Gary Cole), a straight-laced ex-military man hellbent on teaching her discipline, easy-going teenager Kelly Collins (Hilary Duff) enrolls in the George Washington Military School. Kelly struggles to adjust to the demands of her new environment while facing the abuse of her commanding officer, Jennifer Stone (Christy Carlson Romano). Kelly almost drops out — until she falls for a hunky classmate (Shawn Ashmore) and decides to join the drill team.
Jenny Taylor (Amanda Bynes) is a fan of Jason Masters (Chris Carmack), a world-famous rock star, but her efforts to meet him are always thwarted by her nemesis, Alexis (Jamie-Lynn Sigler). Hoping to get another chance, Jenny takes a job at Masters’ favorite Caribbean resort, joined by her best friend Ryan (Jonathan Bennett). Jenny sneaks aboard a party vessel Jason is on, and when Jason is washed overboard, Jenny jumps in to save him. Though the pair find themselves marooned in a secluded cove of a seemingly-deserted island, Jenny soon discovers that they have landed a short distance from the resort. She lets him believe they are stranded so she can make him fall in love with her.
