Robert Rodriguez: Robert Rodriguez, who wrote and directed the "Spy Kids" movies, says he's developing a fully 3-D family film based on an idea from his 5-year-old son.

At a launch party for the "Spy Kids 3-D: Game Over" DVD and other Buena Vista Home Entertainment releases Monday night (Feb. 2), Rodriguez -- dressed in his characteristic Western gear and cowboy hat -- tipped his hat about the ultra-secret project.

"I really enjoy making movies 3-D, and I was enhancing it for the DVD at home in my garage in Austin and then they came to me with the idea of doing another movie in 3-D," Rodriguez tells "I can't give away too many details about it right now, though."
