participating in an advance screening and doing press interviews to promote Broken City. Mark Wahlberg answered questions about Transformers 4. A source reports hearing that Wahlberg said he is house hunting for a rental to use while filming Transformers 4 in the Chicago area during the summer.
The idea really isn't much of a stretch as Michael Bay frequently praised the city when they hosted him while filming his huge scenes for Transformers: Dark of the Moon that often required him to alter and close many major streets. Since the fourth movie takes place 4 years after Dark of the Moon, its possible that the Decepticons are not yet done with the city or possibly fallout from the siege has a part in the film. No other details yet but hopefully learn more as the local press post their interviews closer to the January 18 release date of Broken City.
