Lover boy Karthik was the heartthrob a few years ago. He however did not attempt to evolve himself and hence was stuck. Thus, film offers began dwindling. Now, he is attempting to launch his son as a hero. On the sidelines, he is slowly testing waters in the small screen. In the TV channel, Thamizhthirai he is hosting a game show called Zig Zag Zoom for which shooting commences shortly. His co-host for the show will be Senthil, the comedian who reveled as the underdog in the company of Koundamani. Seems like male actors are taking the cue from female stars a la Khushboo, Devyani and Sukanya in trying for a second innings in the small screen.
