House
The house I'd like to have is the beach house in Nanny Diaries. From the inside, though, I'd make it look more classy rather than sea-ish.
Car
The Aston Martin in Casino Royale. Pearl Blue and chrome rims. Yum. Yum yum.
Jewelry
Elizabeth wears her necklace while deciding what to wear for meeting Raleigh to listen to his story. I'd sell my (worthless) mother for that necklace.
Weapons
The two Desert Eagles the ultimately cool Yun-Fat Chow uses in Bulletproof Monk (without actually firing bullets) and Jessica Biel's character weapons in Blade: Trinity.
Sidekick
Foxy Cleopatra of Goldmember
