New Delhi, July 27 - Its songs have already become a hit and the promos are good, but 'Love Aaj Kal' is an acid test for actors Saif Ali Khan and Deepika Padukone as their last couple of films have turned out to be duds at the box office. There are indeed lots of expectations from this romantic comedy that releases Friday.

Despite giving 2008's first hit in 'Race', Saif's 'Tashan', 'Thoda Pyaar Thoda Magic' and animated venture 'Roadside Romeo' (voice-over) fell flat at the box office. So did Deepika's much-hyped 'Chandni Chowk To China' opposite Akshay Kumar.

'Love Aaj Kal' is not only Saif's first outing this year, it is also his debut as producer.

''Love Aaj Kal' is garnering a lot of buzz. In fact it is after long that a proper love story is coming on screen. The concept is novel and will draw a good initial. It is also expected to re-boost Saif and Deepika's career after their flops,' Delhi-based distributor Joginder Mahajan told IANS.

'The promotion of the film has been very good and the songs are already a hit. Moreover Saif is in a double role in the movie, which will be something to watch out for,' he added.

Directed by Imtiaz Ali, the movie has been co-produced by Saif, Dinesh Vijan and Sunil A. Lulla.

Also starring Rishi Kapoor, Shweta Gulati and Rahul Khanna, the movie is said to be a remake of Taiwanese film 'Three Times', which the producers have denied. Neetu Singh also makes her comeback with the film in a cameo.

''Love Aaj Kal' is one of the most relevant films to come out in a long time...it looks at relationships in a very new light and a very new language,' Vijan posted on the movie's official website.

'The film's storyline is such that any common man can relate to it.
