The makers of Ajay Devgn’s upcoming film 'Thank God' are taking all measures to stay away from controversy ahead of the release of the film. In a new development, the makers have changed the name of Ajay’s character in the film from Chitragupt to CG and his associate Yamdoot’s to simply YD. This, and three other modifications, were done by the makers while submitting the film for certification, says a source.
