Facing flak from fellow Tamil actors that he tendered an 'apology' for remarks during the Cauvery row to ensure release of his film 'Kuchelan' in Karnataka, film star Rajnikanth [Images] declined to join issue saying he would not like to add anything more to the 'speculation'.

"I don't want to add anything more to the speculation," he said here in an apparent reference to criticism by Tamil film stars taking exception to his 'apology' to mollify pro-Kannada groups which had threatened to disrupt the movie launch in Karnataka.

He, however, reiterated that his talk of "kicking" those in Karnataka against the water project was aimed at persons indulging in violence in the name of protests, and not aimed at Kannadigas as a whole.
