Dimension Films is behind this reboot for the moneymaking franchise, which initially starred Alexa Vega and Daryl Sabara as the kids of superspy parents (Antonio Banderas and Carla Gugino). Robert Rodriguez wrote and directed each installment.
The new movie centers on Jessica Alba's character as a retired spy who has been reactivated and is a mother of a baby and two preteen stepchildren.
The actors cast in the preteen roles will be the new Spy Kids.
Other roles seeking to be filled include Jessica Alba's husband, a slightly nerdy investigative reporter, and the villain, known as the Time Keeper, whose goal it is to stop time.
Spy Kids 4: All the Time in the World will shoot in Austin. The movie, with a budget of less than $30 million, is eyeing a start next month.
The picture, which also has been known as Spy Kids 4: Armageddon, will be in 3D.
