What will players have to do to win $1 million?

More than 500 people eager to win $1 million from Mark Cuban attended an open casting call for the Dallas Mavericks owner's upcoming reality television show.

Sixteen people will be chosen from auditions in five cities and from submitted video applications. But there's still no word on what it will take to win the money on the ABC show "The Benefactor."

"It's like 'Willy Wonka & the Chocolate Factory,' " Cuban told the Dallas Morning News for its Sunday editions. "When you walked into Willy's factory, you had no idea what the game was."

Contestants will live in a Dallas house for three weeks and participate in activities Cuban devises.
