Akshay Kumar as the teacher.
Paresh Rawal as the kid's dad.
It would be a brainless comedy. The kid's dyslexia would be made fun of. Half the times the parents will be running after the kid from one room to the other and that, in the director's opinion, would be funny.
The film will be full of sex jokes. So for example, when Akshay would come to the parents telling them that their son has dyslexia, the ignorant father would say something inappropriate like 'iss umar mein? par kaise, woh to hamesha boys school mein padha hai!'. And yes, the director would think it is funny.
In the climax of the film all the characters in the film would run around in the amphitheater for no reason, spilling colors on each other. That's where the film will end, without any logical conclusion.
And of course, Paresh Rawal would emote like an epileptic himself making us question the boy's mental abilities anyway.
