During a recent talk show appearance, Tollywood star Allu Arjun expressed his admiration for Bollywood actor Ranbir Kapoor, calling him one of the industry's finest. This prompted the show's host, veteran actor Nandamuri Balakrishna, to propose a multi-starrer featuring the two actors, even suggesting he'd write the script himself if necessary. This has prompted fans to think that the next film is 'Dhoom 4'.
