‘Corvalis’ recently sent us a report which said that filming for X-Men 3 took place on July 24th in San Francisco. The filming involved a camera looking towards Alcatraz. He has now confirmed that the shooting is for the trailer:
Once again, (today) I came across the same crew filming crew of X-3. However, this time they were on Alcatraz. This time I was able to talk to one of them. They confirmed it was for X-3, and this was primarily for the X-3 trailer. They said it should be due out sometime before Christmas. The bad news is, I got there and saw them after they had filmed and they were packing up.
Stay tuned for more news on the trailer as it comes in.
