Film director Phil Lord has fond childhood memories of days spent playing with Lego's colorful plastic blocks. He says he would simply dump what he had on the floor and create a huge mess.

"I never remember picking them up," he says. He also did not have the patience to create what the instructions on the box told him to.

Fellow director Christopher Miller, on the other hand, says his son is currently hooked on the brick toys, but he first builds exactly what the instructions dictate. "Then he will make his own vehicle, each time more ridiculous than the other," he adds.
