Spoilers
Brad pitt is involved in it as the main hero. Based strongly on the book World War Z, and is being filmed in Glasgow Georges Square (decked out like Philly) and Grangemouth BP plant. Part of it is also being filmed in Malta as well.
Looks interesting, and I might just watch it!
Edit
Turns out my niece actually took some pictures on set....Quite scary actually.
