There are rumors floating around that the Hannah Montana / Miley Cyrus Best of Both Worlds Concert Tour movie will be in theaters longer than the original one week period that it was supposed to be. There have been reports of individual theaters choosing to run the movie for two weeks. There is also a rumor that Disney has extended the run to three weeks for all theaters.
It is good that fans will have an extended time to see the movie, but it is a little bit unfair to those who rushed out and changed their plans to see the movie the first week when they just could have waited.
These are just rumors though, I have not seen anything official yet.
