While filming "World War Z" in Glasgow, Scottland, today The Metro Sandwich Company honored Brad Pitt by creating "The Brad Pitt Special Panini," which Brad's assistant collected for the star's lunch.

We see a lot of red sauce and cheese, but we're not sure what kind of meat is included. Pitt returned the gesture by signing the poster: "w/ extra onion & jalapeno...a delight for the senses. Many thx, BP." Check out how neat his handwriting is!

The actor is in the Scottish city with his partner Angelina Jolie and their six children, who have been spotted out and about over the last few days.

Max Brooks' epic tome of a fictional time of global war against the undead is brought to life in "World War Z." Pitt stars as a journalist covering the disaster.
