Will Smith is so proud of his family he is convinced they will be a success - insisting everything he touches turns to gold.
The Hancock star jokes that just sharing his family name is enough to guarantee scoring a hit movie.
But he has a warning for Hollywood chiefs looking to cast his children in a film - his daughter could let success go to her head.
Smith's son Jaden has appeared alongside him in The Pursuit of Happyness, while daughter Willow was his co-star in I Am Legend.
He tells Access Hollywood, "Put any Smith in there, it's Number One... (Jaden's) just well adjusted. Willow is the one. That's the one I have to keep my eye on - don't let her get to Number One!"
