Bollywood star Hrithik Roshan is to undergo brain surgery after sustaining an injury on set while filming his latest movie Bang Bang. The actor was admitted to the Hunduja hospital in Mumbai, India on Sunday (07July13) to have an operation to remove a clot which developed after he hit his head while shooting the film, opposite Katrina Kaif, two months ago. Roshan, 39, alerted fans to his impending surgery with a post on his Facebook.com page which reads, "We all know that we create a life of joy using the power of our mind. I've had the privilege of creating wonders with this amazing gift given to us called the brain. "Occasionally one must look within and realise its value. It gives us the power to see, hear, touch, smell and taste, it allows us to conquer fear and create courage to do things we never imagined. Maybe it's time for me to feel the power literally. "I am going to go through brain surgery today and want you to know that I am going in with absolute power to recover fast. My thanks to all of you for using the power of your mind to contribute to my life." He later added, "Minor brain surgery to remove blood clot (chronic subdural haematoma). Should be rock n rolling by evening! U (you) guys have a great day too! Supersonic!!"
