Karan Johar and Ram Gopal Varma have a history of engaging in Twitter wars but the 'My Name Is Khan' director says he now wants to pick on someone else as RGV is "so last season" in his life.
Johar, 41, said their exchange of words on Twitter are just for fun.
"It is fun. We are having fun actually. It is war of words for everyone's entertainment. According to me, right now, I really want to find a new filmmaker to pick on because he is so last season in my life," Johar, who was in the city to promote 'The Lunchbox', said when asked about his Twitter exchange with RGV on Teachers Day.
Varma, 51, had initiated the fight by poking fun at Johar's 2012 hit film 'Student Of The Year' on Teachers' Day.
"If someone takes off from Karan Johar's 'Student of the year' and makes Teacher of the year it will become the Disaster of the year," RGV had tweeted.
Johar had promptly tweeted: "Disaster of the year is your territory Ramu... no one can ever replace the comfortable place you have made for yourself there."
It was not for the first time that the two filmmakers fought on Twitter. In 2010, RGV had made fun of Johar's 'My Name is Khan'.
Johar has collaborated with Disney-UTV for the Ritesh Batra directed 'The Lunchbox', which hits theatres on September 20 with 600 prints in India.
The director, who is famous for his larger-than-life take on romance, said he decided to attach himself to the film because he was envious of its simplicity.
"I envy that the film was not completely mine, envy that it had the most beautiful writing and a simple story told in a way that I could never write. So I decided to substitute envy with acknowledgement. If you can't beat them, join them."
Johar admits that he is incapable of making simple films but says as a producer he wants to nurture such projects and learn from new directors.
"Every film is a new mistake. Looking back I find, 'Kuch Kuch Hota Hai' a ridiculous story, when I see 'Kabhi Khushi Kabhie Gham', I think it is 35 minutes too long, 'Kal Ho Naa Ho', I wish I had changed the end..., 'Student of the Year', I wish it had more of emotional intensity," he said.
Johar is planning to direct next year in September. "I have the story and I am working on the screenplay."
