Mahesh Babu is undoubtedly the leading star in Tollywood now. There may be debates about his position as number one hero, but inarguably he is leading the pack of Telugu superstars at this point. For some reason Mahesh didn't try to extend his business frontiers beyond Tollywood.
Most of our actors are making plans to conquer other states like Tamilnadu and Kerala. Allu Arjun has already earned so much name and fame in Kerala. Ram Charan and others are following the suit. Mahesh despite being a super power in Tollywood market never tried to set his foot in other states. Businessman was supposed to release in Tamil and Malayalam along with Telugu. But that didn't happen.
Finally it is happening with Dookudu. This film is the biggest hit in Mahesh Babu's career till now. The makers of Dookudu believe that it will work in other languages too and are releasing the dubbed version of Dookudu in Kerala shortly. Recently Malayalam version's audio was launched too. Hope it leaves a strong impression so that all of Mahesh's future ventures get a simultaneous release in Malayalam.
