The ever-sexy Jessica Alba has signed on for the fourth Spy Kids movie, ‘All the Time in the World’.

Previous roles in films such as ‘Sin City‘ and ‘Machete’ has impressed those who matter, the producers choosing her for a spy role in this new film. There’s hope to find much of the original stars in this latest picture, although the two lead characters (Alexa Vega and Daryl Sabara), not being kids anymore, are more likely to be appearing in smaller, supporting roles. Banderas is a key player in this one and should be pairing up with the ‘retired’ spy (Alba) to defeat the evil, time-stopping Time Keeper.

Expect it summer ’11.
