Mumbai, July 8 - After making candy floss romances, Karan Johar is dealing with serious issues in his 'My Name Is Khan', which brings Shah Rukh Khan and Kajol together on screen after a long time. Though he is excited about presenting a different side of Shah Rukh, making the film did turn unpleasant when actor Aamir Bashir was denied a visa to the US.

Karan's latest directorial venture is 'diametrically opposite' to his earlier films.

'You know, on the very first day of shooting my cameraman Ravi Chandran looked at me and said, 'I don't think you've ever shot something like this'. Shah Rukh plays a completely different human being ... I've never directed that person before,' Karan Johar told IANS in an interview.

But he had his share of problems too.

'Yes, there were problems. We had certain legal issues. We had to make some changes to accommodate the developments. They were sorted out. I believe in completely going by the law of every land. That's what we did in LA (Los Angeles) when troubles arose,' said Karan, who replaced Aamir with Jimmy Sheirgil in the movie.

Were you upset with Aamir for going to the press about the visa problem?

'I don't see why the issue had to be reported so prominently in the Indian media. It complicated things for me. If creating hurdles for a filmmaker on a difficult foreign location makes news, so be it. It constantly kept creating stress for me,' he added.

Written by Shibani Bathija, 'My Name Is Khan' is about a Muslim (Shah Rukh) who suffers from the Asperger syndrome, a form of autism that impacts social interaction abilities, and he is arrested as a suspected terrorist in post-9/11 Los Angeles after authorities mistake his disability for suspicious behaviour.

Excerpts from the interview:

Q: You could make a film on the things that happened during your Los Angeles schedule of 'My Name Is Khan'.

A: Besides normal problems, there were unforeseen problems. Thank god for my fabulous technical team. Without them I could never make my film the way I want to. Yes, there was stress.

Q: There were visa problems for some Muslim members of your cast?

A: Yes, there were problems.
