Cher John

On its opening weekend in the United States, it went to number one, becoming the film to finally end the reign of James Cameron's Avatar (2009), which had sat at the top of the box office for seven consecutive weeks.

When John is in Hungary when he hears about 09/11 (as indicated by the signs on/near the coffee shop: Tigris Kavehaz, Muvesz...), and the TV news are in Serbian (even using Cyrillic - not Latin - script). This scene is not necessarily a mistake. Although not well explained in the movie, in the book John was stationed in Kosovo. He could simply have been standing outside a Hungarian-style coffee shop there, which explains the Hungarian language on the store front. Serbian is recognized as an official language of Kosovo, which explains the TV news being in Serbian.
