'Very few actresses can perform like her. Doesn't every director want to work with Kajol?' Ajay told.
'Working with her is a delight. When a writer writes his book, he uses words to express himself and when a director makes a film, actors like her help convey the message rightly,' added Devgan, who was in the capital Saturday to promote his upcoming film.
The actor denies he would only select Kajol for his future projects.
'Taking her in my first film doesn't mean that I would only work with her. Casting depends on who suits the role most, and for this character she fitted the bill.'
Apart from Ajay and Kajol, the movie also stars Divya Dutta, Karan Khanna, Isha Sharvani and Sumeet Raghavan. It narrates the story of three couples and how the successful marriage of one couple helps mend another's relationship and how the third is urged to tie the knot.
'I have not tried to make a pseudo intellectual film, instead a commercial one. 'U, Me Aur Hum' is about love, life and relationships. The aim is that people must come out of the theatre with a smile and feel good,' the national award winner said.
Ajay believes directing a film and acting in it is not difficult.
'Doing two things at a time requires a lot of hard work but once you are clear about what you want to do it is not that difficult.
'Moreover, direction wasn't a big change for me. I started my career as a director. I used to make small films and would do everything except acting in them. I always wanted to direct a full-length film,' he said.
'It all started with a thought that gradually took shape. Only when a second thought comes along will I roll out my next film.'
Commenting on whether his role in the film is a reflection of his personal life, he said: 'No, there are no similarities.'
'For instance, in the film the character falls in love at first sight but nothing like this has ever happened to me in real life. However, I believe in what the character believes in.'
