Mumbai (PTI): All eyes will be on Bollywood box office on Friday with the release of 'Love Story 2050' and 'Jaane Tu..Ya Jaane na' featuring two promising debutants Harman Baweja and Imran Khan respectively.

Both come from film families and are contrasting personalities.

With the first half of 2008 not providing much fireworks at the box office, trade analysts are pinning hopes on these two films to lead the way in the second half.

Harman is the son of filmmaker Harry Baweja while Imran is the grandson of noted filmmaker late Nasir Hussain and nephew of Aamir Khan.

Harman makes his debut under the directorial baton of father Harry in the film produced by his mother Pammi. Imran takes his bow as an actor with lyricist turned director Abbas Tyrewala and Aamir as producer of the film.

Tall and handsome Harman has been compared to Hrithik Roshan because of his looks and dancing skills while Imran with his typical choclate boy looks remind the audiences of a young Aamir Khan.

Harman is trained in film production and always wanted to be an actor and Imran studied filmmaking at New York film school aspiring to be a director. Acting happened just by chance to him.

Both Harman and Imran begin their careers with romantic films -Harman with a sci-fi, futuristic love story and Imran with a contemporary romantic tale set up in the backdrop of a college campus.

The premiere of 'Jaane Tu..' was a star studded affair held at a suburban multiplex on Thursday night. While "Love Story 2050" premiered in London the previous day.

Trade analyst Amod Mehra told PTI that "Jaane Tu" has a fresh,young look to it and this would work in favour of the film.

"It is a routine story presented in a very contemporary manner. The treatment of the story is very good. As the story comes to an end, one feels bad about it and want to see it more.It is after a long time that Bollywood has seen a simple love story which has some brilliant light moments," he said.

Apart from Imran,Pratik Babbar,son of late Smita Patil and Raj Babbar makes a confident debut as the leading lady Genelia's brother.

Mehra said clash of release dates of the two films is bound to affect one of them. "It is natural that the better film of the two will work at the box office," he added.

"Love Story 2050" marks the biggest ever global release for a debutante actor. The film has opened at 1055 screens across 898 locations worldwide.
