James Cameron’s Oscar-sweeping box office smash may have been set on the high seas, but it wasn’t made anywhere near the icy cold of the Atlantic. Instead, this 1997 story of star-crossed lovers was filmed in the warm waters lapping into Rosarito, Mexico. Tucked on the Baja Peninsula just 16 kilometres south of San Diego, Rosarito later became the go-to spot for many big budget Hollywood adventures, including Pearl Harbor.
