Movie Cave Must-Haves

Ok guys, this is a little off topic but I am about to set up my own movie cave in my basement, a little like a man cave but purely for movies. I already have a 40-inch plasma screen, blu-ray player, etc. Can anyone recommend any furniture, items, at an affordable price that I should purchase.

Popcorn maker and a fridge filled with those mini-barrels of fizzy drinks.
