Bollywood superstar Shah Rukh Khan, who recently injured his hamstring while shooting an action sequence for Fan in Croatia, has not let the injury dampen his enthusiasm or energy, it seems.

Taking to Twitter, SRK recently wrote, ''I hav this belief that if I run fast enough I will take off!! Trying…& waiting for critical take off speed…one day!'' The King Khan has injured himself quite a few times while shooting for his films, but the superstar still continues to amaze everyone with his unflagging energy and larger-than-life attitude.

Apart from Fan, Khan will also be seen in Rahul Dholakia's Raees and Rohit Shetty's Dilwale.
