Director Saran, who loves to dabble in scripts featuring dons, is back with Market Raja MBBS that stars Arav, Radikaa Sarathkumar and Kavya Thapar in the lead. This film, too, has a don connect. But that’s nothing got to do with his earlier subjects, says the director. “Radikaa plays Arav’s mother, who is a don in Perambur. She has stepped into her father, MR Radha’s shoes to play this character. She will be mimicking MR Radha sir’s body language and voice modulation to a certain extent,” he says.
