When James Cameron was directing The Abyss in 1987, he opted to film the underwater at the unfinished Cherokee Nuclear Power Plant near Gaffney, South Carolina. After filming wrapped, the set stood basically unattended for 20 years, allowing urban explorers to sneak in.

According to the interwebs, the set was demolished in 2007, but we still have this fantastic documentary footage (2, 3, 4, 5, 6) showcasing how James Cameron created the bottom of the sea in the Deep South.
