Ajay Devgn and Salman Khan have been good friends for many years now. However, it seems that this friendship may not last a long time. Ajay is working for quite some time on his ambitious venture Sons of Sardaar: The Battle of Saragarhi. The movie is a big-budget war film based on the 1897 battle between 21 Sikhs and 10,000 Afghans. Ajay was apparently in for a shock when Salman Khan and Karan Johar announced their project based on the same battle. A leading daily reports a source as saying, "Ajay did not believe the news initially. He considers Salman family. However, when he was sure, he sent across an emotional message to Salman saying he had not expected Salman to hurt him like this. He said to Salman that it was unfair to make a film on the same subject that his team has been working for the last two years."
