The trailer of AR Murugadoss' 'SPYder' will most likely be unveiled on Sept 9. The date has got another significance with respect to the film. It's when Mahesh Babu's Tamil debut will be grandly celebrated in the form of an event in Chennai.

Set to hit the screens in Telugu and Tamil on Sept 27, the spy thriller is all done but for one song. It will be shot in the European country of Romania from Aug 23. Post-production works are currently on.

Before the trailer release on Sept 9, Mahesh Babu's fans will have a lot to enjoy in terms of singles. May be, atleast one song will be out before the end of this month.

Meanwhile, ARM has suggested in an interview that SJ Suryah, who is the antagonist, mostly operates surreptitiously. He is always engaged in a battle of wits and it's up to the intelligent cop, the hero, to nab him. Because the villain operates rather secretly, he is all the scarier.
