World War Z is currently in the middle of filming, but according to THR, Bryan Cranston is negotiating for a "small but flashy" role in the film. Bryan Cranston can be seen in AMC's Breaking Bad and also has a role in the upcoming Total Recall reboot as Vilos Cohaagen.

Brad Pitt, Mireille Enos, James Badge Dale star in the adaptation of the Max Brooks novel, with Marc Forster (Quantum of Solace) directing.

“‘World War Z’ tells the story of the world’s desperate battle against the zombie threat with a series of first-person accounts ‘as told to the author’ by various characters around the world. A Chinese doctor encounters one of the earliest zombie cases at a time when the Chinese government is ruthlessly suppressing any information about the outbreak that will soon spread across the globe. The tale then follows the outbreak via testimony of smugglers, intelligence officials, military personnel and many others who struggle to defeat the zombie menace.”
