Mukesh Ambani-led Reliance Industries is in talks to buy a stake in producer Karan Johar's Dharma Productions, The Economic Times reported. Karan has been seeking to monetise his stake in Dharma for a while but previous deals have failed due to differences over valuation. Reliance already owns stakes in Jio Studios, Viacom18 Studios, Colosceum Media and Balaji Telefilms.
