SRK and Hrithik's respective movies, Raees and Kaabil released on the same day, leading a great amount of animosity between the two actors.

Looks like they are not yet ready to leave their grouse behind. Recently at an event the two stars came face to face, but they are said to have not even exchanged pleasantries.
A source says, "They obviously spotted each other at this event but neither SRK nor Hrithik wave or smile. Both chose to royally ignore the presence of other and didn't even glance at each other."

Looks like this fight will take a lot of time to get resolved.
