According to THR, Jessica Alba (The Killer Inside Me, Fantastic Four) is in talks to star in Spy Kids 4, writer-director Robert Rodriguez's planned reboot (of sorts) of the family-oriented Spy Kids franchise. Like Spy Kids 3-D: Game Over, Spy Kids 4 will be, for better or for worse, released in 3D. Rodriguez obviously liked what he saw in Alba's supporting roles in Sin City five years ago and Machete, the low-budget, Mexploitation flick that opens September 3rd, to bring her back for a role in his next film.

In Spy Kids 4, Alba will play a former spy, the mother of a baby (like Alba in real life) and step-mother to two preteen children. The stepchildren will take over the "Spy Kids" mantle first worn by Alexa Vega and Daryl Sabara. In the previous installments, the parents, played by Antonio Banderas and Carla Gugino, were supporting characters. If that's the case, Alba might be the most or second most, depending on who signs on to play her husband in the film, credit, but be off-screen for long periods of time.

While the other roles have yet to be cast, Banderas, Vega, and Sabara are expected to appear in Spy Kids 4, presumably in cameos or significantly smaller roles. Spy Kids 4 will be shot in Austin, Texas at Rodriguez'a Troublemakers Studios with a reported $30 million dollar budget. Principal photography is expected to begin next month.

So what do you think of Alba starring in Spy Kids 4? Alba has never been known for her range or gravitas (see The Killer Inside Me for an exception, though), so a light, comic role in a film like Spy Kids 4 seems perfectly (or is the right word "adequately?") suited for her talents.

Spy Kids 4 is set to open next August.
