The two Khans will be seen as wrestlers in their respective films. There were reports that after watching the trailer of 'Sultan', Aamir felt 'Dangal' would suffer.
"Aamir is scared? He is doing 'Dangal' and he is scared! Then why did he do 'Dangal'? Why would Aamir be scared (of 'Sultan')," Salman said in an interview here.
"My film is different than his. Both of us knew that the two films are about wrestling. In that case, does it mean that if Shah Rukh Khan is doing a love story then I won't do it? I have heard Aamir's (film) script and it is outstanding," the 50-year-old actor said.
The Ali Abbas Zafar-directed film 'Sultan' centres around the life of a wrestler Sultan Ali Khan.
'Dangal' is the biopic of wrestler Mahavir Singh Phogat (Aamir), who taught the sport to his daughters Babita Kumari and Geeta.
'Sultan', produced by Aditya Chopra, will arrive in theatres next month during Eid, while 'Dangal' is set to release in December this year.
The 'Dabangg' star joked that if given a choice, he would have done 'Dangal' as well.
"I would have done both the films. It would be 'Sultan' first and then 'Sultan's Dangal'," he said in a lighter vein.
Salman revealed that he shared his "Sultan" trainer with Aamir to help him prepare for "Dangal".
"I am a very big hearted man," he said.
Gossip mills are abuzz that Salman-Aamir starrer 1994 hit comedy "Andaz Apna Apna" is getting a sequel. When asked about reuniting with Aamir on the film, Salman said, "I have been dying to work with Aamir for the longest time."
