Haasan, who met Rajinikanth at his residence in Chennai today, said that the meeting was not political but a courtesy call.
"It's a courtesy call, not a political meeting. I came to inform him about my political tour. He wished me good luck," he told media after the meeting.
On being asked if the duo was planning to enter into an alliance, Haasan said, "Only time will tell".
He also met Dravida Munnetra Kazhagam (DMK) President M. Karunanidhi and the party's working President M.K. Stalin at their residence.
Haasan's remarks came days after he said that any political tie-up with Rajinikanth seems unlikely, as latter has a "hue of saffron" in his politics, in an apparent reference to the BJP.
"There is a hue of saffron in Rajni's politics. If that doesn't change, then I don't see an alliance with him," he said, during the launch of his website, naalainamadhe.maiam.com, at Harvard University.
Meanwhile, Rajinikanth extended his best wishes to Haasan and said that "he was not entering into politics for fame or money but to serve people of the state."
"Kamal (Haasan) wants to serve the people of Tamil Nadu. I pray to God that he attains success," the actor said.
Haasan will announce the name of his political party during a statewide tour starting February 21.
