In recent times, the trend of using a temporary working title for the time being and announcing the title at a later point of time before the film's release increased a lot. But, unfortunately, some of the crazy working titles are facing trouble as some other production houses are registering the same titles for their upcoming films. One recent example is the working title of Prabhas' Jaan which got registered by Dil Raju (Jaanu). Now, as per the latest buzz, Vijay Deverakoda's Fighter might also land in trouble as the makers of Mega hero Varun Tej's next are planning to register the title. Interestingly, both the films are based on boxing sport, and the leads Vijay and Varun will be playing professional boxers.
