Vijay's Mersal had KDM issues this morning, and the first shows were delayed by an hour at all the theatres in Tamil Nadu. However, later it was revealed that the KDM key had been given only for today (18th Oct), and not for the remaining days.
 

Now, it looks like all the issues are sorted out completely, and Mersal will now run smoothly without any issues. Aditi Ravindranath, the executive producer of the film from TSL confirmed this news with her tweet, "#MERSAL KDMs on from tomorrow till eternity #BlockbusterMersal"
