On one of the first nights of shooting, Fincher and his crew were in Sweden, filming a murder scene that takes place alongside a gloomy dock. But after a night's work, Fincher didn't have the shot he wanted, and the film's ultratight schedule meant he wouldn't be able to return for months.

When Fincher began planning the reshoot, he learned that the property had been sold to one of the guys in ABBA. Apparently, the new owner—either Benny or Björn, it's not really clear—wasn't thrilled at the prospect of having his evening stroll interrupted by a simulated drowning, and he refused to let the crew come back. Rather than find a new location or make do with the footage he had, Fincher decided to build his own Swedish dock.

"ABBA's dock isn't cool. You know what's cool?"
