The two are engaged in a verbal fight ever since Varma provoked Johar by expressing his desire to remake 'Raavan' as 'My Name Is Raavan'.
'I want to remake 'Raavan' and I want to request Mani to remake '(Ram Gopal Varma Ki) Aag',' Varma posted as a reaction to Mani Ratnam's recently released 'Raavan' on his Twitter page. It was followed by another post: 'I (have) got a better idea... I will make 'My name is Raavan' and Mani should make 'Raavan Ki Kurbaan'.'
The comment was an indirect dig at Johar's movies 'My Name is Khan' and 'Kurbaan'.
Varma did not even spare superstar Shah Rukh Khan and commented on his upcoming sci-fi project 'Ra.One'.
'Let's all hope and pray that 'Ra.One' does not become 'SRK ki Baarish'. Let's all hope and pray that 'Ra.One' does not become 'SRK ki Aag',' he added.
Johar, who was infuriated by Varma's comments, replied: 'You have an amazing sense of humour Ramu (Varma)! Never shows up in your films though.'
On that Varma said: 'Karan, because of the constant bashing I receive, I developed my sense of humour as a defence mechanism. And talking of my films not having humour, check out the great comedy I made called 'RGV Ki Aag'.'
