Question: What year did the movie come out that is currently the theme for Disneyland's Submarine Voyage?
Context: The Main Street Electrical Parade is a nighttime parade, created by Bob Jani and project director Ron Miziker, famous for its long run at Disneyland at the Disneyland Resort in California and Magic Kingdom at the Walt Disney World Resort in Florida.  It features floats and live performers covered in thousands of electronically controlled lights and a synchronized soundtrack triggered by radio control along key areas of the parade route.  The parade has also spun off several other versions that ran or continue to run at Disney parks around the world.  Currently, an updated version runs at Tokyo Disneyland as the "Tokyo Disneyland Electrical Parade: DreamLights".  In 2014, Hong Kong Disneyland premiered a spiritual successor to the Main Street Electrical Parade, the "Paint the Night Parade", which, like its predecessor, features "Baroque Hoedown" as its theme song.  An extended version of "Paint the Night" premiered at Disneyland on May 22, 2015 as part of the park's 60th anniversary celebration. Starcadia is an EP by Joy Electric.  The concept of Starcadia is based upon rides that have existed in Disneyland: Matterhorn Bobsleds, Space Mountain, Starcade, Submarine Voyage, and Carousel of Progress.  Musically it was described as "more cosmic and spacey" than the band's prior releases. The Submarine Voyage was an attraction at Disneyland in Anaheim, California.  The attraction, which featured ride vehicles designed to resemble submarines, opened on June 14, 1959, as one of the first rides to require an E ticket.  It was part of a major expansion of Tomorrowland and Fantasyland, which also included the Matterhorn Bobsleds roller coaster, an expanded version of Autopia, the Disneyland Monorail, and the Motor Boat Cruise.  The Submarine Voyage closed on September 9, 1998; at that time, it was reported that the attraction would reopen with a new theme by 2003, but that did not occur.  The attraction ultimately reopened in June 2007 themed to Disney·Pixar's "Finding Nemo", and now operates as Finding Nemo Submarine Voyage. Disney California Adventure is a Disney theme park in Anaheim, California, adjacent to Disneyland and part of the larger Disneyland Resort.  It opened on February 8, 2001.  Here is a list of the current attractions found therein, arranged by "land" and with brief descriptions.  These are only attractions from the Disney California Adventure itself, not from Disneyland park or other parts of the Disneyland Resort, and that parades and character meets are not listed in this article.  (The term "attractions" is used by Disney as a catch-all term for rides, shows, and exhibits.)  Disney California Adventure currently has 34 attractions in the theme park. "Voyage" is the 28th single released by Ayumi Hamasaki on September 26, 2002.  "Voyage" debuted at #1 on the weekly charts with more than 319,020 copies sold in its first week and remained at the top position for three consecutive weeks out of a total 28 weeks on the chart, becoming her longest-charting single.  The single sold a total of 679,463 copies and became the ninth-best-selling single of the year.  To date, "Voyage" is Ayumi Hamasaki's only single which has remained in the top position of the weekly Oricon charts for at least three weeks other than "H" and "A"; however, "Voyage" is Hamasaki's only single to stay at #1 for three consecutive weeks ("A" and "H" spent 3 non-consecutive weeks at #1).  "Voyage" was used as the theme song of the Japanese movie "Tsuki ni Shizumu", which was created in lieu of a PV for the single.  It was also used as the ending song of a Japanese television drama "My Little Chef", starring Hiroshi Abe and Aya Ueto.
