Spider-Man: Brand New Day Advance Booking

Makkale, I just noticed that one theatre in Chennai has already opened advance bookings for the new Spider-Man movie. Does anyone know when the other main theatres (Sathyam, Palazzo, IMAX, AGS, etc.) will open theirs?

Usually avanga 5 days before dhaan open pannuvanga, but since one screen is already open, I'm worried I might miss the FDFS tickets. Theatres la irundhu edhavadhu insider info irukka? Epodhu open aagum nu therinjavanga sollunga!
