Bollywood actor Ajay Devgn, who has just bagged the Stardust award for Reader's Choice best actor in comedy for "All The Best", says his forthcoming film "Atithi Tum Kab Jaoge?" is a hilarious movie but unlike any slapstick comedy.

"It is not a slapstick comedy. It's a lighthearted film. This comes under a different genre. There is sensibility along with humour. There is also an undercurrent emotion in it. After a long time I did a film of this kind, " Ajay told reporters at the official launch of the upcoming film's website here Monday.

The film, directed by Ashwani Dhir, revolves around the story of Puneet (Ajay Devgn) and Munmun (Konkona Sen Sharma), a happily married couple living in Mumbai. Their life takes a turn when a distant relative Chachaji (Paresh Rawal) turns up unannounced at their doorstep from a far off village.

The chaos that follows makes it a rib tickling comedy where the agonised couple tries out various methods to get relief from him but fails time and again. The film is set to release Feb 26.

"There are mainly three characters and it's a problem between the three of them, " said Ajay.

Konkona has always been offered serious roles and "Atithi Tum Kab Jaoge?" would be her first full-fledged comedy.

"I am mainly seen as a serious actress... I am usually not given a chance to do films which are more lighthearted in nature. That's why I am very grateful to the director and producer of 'Atithi...' that they thought of me for this character. I really enjoyed doing it, " said Konkona.

"I think people will relate to the film a lot because this is basically reflecting on the lives of young couples today in Mumbai. There are people from all over the country coming here to make their lives.

People are struggling and if they have guests coming from their village, there is a question of privacy. It's not like Delhi where you have huge sprawling houses. So I think because of all these factors people will relate to it, " she added.
