You might consider yourself a Batman fan, but the caped crusader's biggest fan has to be Chris Weir. After checking out his incredible Bat(man) Cave, I'm pretty sure you'll agree that Batman fans don't come any more intense than this.
Weir spent two years and $120,000 turning his basement into the ultimate Batcave replica, and the results show. Seriously, Weir's Batcave even has an entrance that is activated by a hidden door that's activated by a shiny red button. Beyond that, the Batman Fan's basement is loaded with a crazy amount of memorabilia, including a full sized replica of the Batman suit worn by Christian Bale in The Dark Knight Rises.
Of course, no Bat(man) Cave would be complete without a completely decked out home theater, and Weir's seems like the perfect place for a Dark Knight marathon.
