Will Smith and Jada Pinkett Smith's little boy JADEN is following his mum and dad into the movies after signing on to make his big screen debut in new film THE PURSUIT OF HAPPINESS.

But the role won't be too much of a stretch for the seven-year-old - he'll play the son of Will Smith's character in the project.

The movie follows the exploits of a salesman, who gets custody of his son just as his career as a stockbroker is taking off.
