Definitely, ad film industry and brand promotions are two different beasts. When an actor will be replaced and when someone will be given more money, we never know.
Mahesh Babu is taking care of being the biggest brand ambassador and ad company favorite of TFI. Only person who is contending him is Allu Arjun.
Allu Arjun has two big brands in Frooty and Redbus, which gave him good deals too. But now, Redbus has gone for MS Dhoni to be their brand ambassador.
The company has decided to go with National Superstar Cricketer and Legend, so that they get big exposure, it seems.
Also, as Allu Arjun is busy with three films and business plans like building theatres, developing his own production house, the actor will be busy during 2019-2021 period, it seems. May be deceased workload on him.
From 24th April, the actor will start shooting for AA19 in the direction of Trivikram Srinivas. Soon, he will participate in script discussions with Sukumar too.
