Has Hrithik ever rejected a movie with Vidya Balan?

No but one time vidya pulled an ullu banaya bada maza aaya type joke on hrithik😆

Vidya, dressed as a beggar, approached the actor while he was shooting at a suburban studio and refused to leave until she received alms from him. Hrithik was startled and even called out to his security guards to throw the beggar out. And, when the latter refused, Duggu was even more confused. ..It was only when the unit members and the security personnel burst out laughing that Hrithik realised that he had been taken for a ride. While he couldn't believe Vidya's transformation initially, the two were seen sharing a hearty laugh over it later.

And Vidya's husband is the producer of HR's next (very expensive) movie. His company has had a lot of flops recently too. She has no reason to 'take revenge.'
