Ollivander, the pale-eyed, white-haired shopkeeper (played in the film by John Hurt), makes and sells magic wands to witches and wizards as they enter school or break their old wands. He remembers every wand he has ever sold. To determine the best wand for a witch or wizard, Ollivander measures various body parts (including, in Harry's case, between his nostrils) and then checks the reactions of various wands to the buyer, a process to which he refers as "the wand choosing the wizard".
