The reason for the ban is said to be that she has rejected to be a part of the movie Twenty:20, produced by AMMA, in which all Malayalam celebrities are going to appear free of cost.
When Meera was approached for a role, she did not allocate any dates since she had a clash with the dates of her Telugu movies. Since she did not allot any dates, she was banned. The ban will be effective until AMMA lifts the ban.
How will Meera's career go on if she is not allowed to do movies in her own home state? Just wait and see what happens next!
