Udayanidhi Stalin is soon to debut as an actor in a film to be directed by Rajesh. This film has been titled Oru Kal Oru Kannadi with the tagline Ok… Ok… The launch of this movie is to take place soon and Red Giant Movies, which is producing this venture, wants it to be a grand affair. Sources say that all the previous productions of Red Giant Movies will be screened during the inaugural pooja to make it a novel affair. With so much planning going on, there is one question that still remains unanswered – who the heroine is? The director has said that talks are on to find a suitable on-screen pair for Udayanidhi and they will come up with a good choice soon. Nirav Shah has been roped in to take care of the cinematography for OKOK.
