He plans to adapt Mahabharata for the celluloid but right now, Abhishek Kapoor aka Gattu is suffering a backache of epic proportions upsetting his work schedule.

Mirror has learnt that on Monday night, Abhishek was to attend the premiere of a Hollywood film, Son of God, with Sushant Singh Rajput and Katrina Kaif. But before he could leave the Western suburbs for a journey to South Mumbai, he was struck with a massive back spasm.

"His family panicked as the pain came on suddenly. A doctor was immediately called to take stock of the situation. He figured that it's a spasm but Abhishek was in pain even while resting. He's been advised complete bed rest for at least a week," the source said.

The unexpected back trouble could create a hiccup in the upcoming schedule of Fitoor. But when we called up Abhishek, he refuted this saying, "Yes, I suffered a back spasm the other night and couldn't attend an event and though I have been advised total rest, I can assure you that I will be back on my feet in no time."

He points out that the next schedule of his Aditya Roy Kapur-Katrina Kaif starrer is only in August. "So I have a lot of time to rest," he chuckled.
