Actor Raj Kumar Yadav, who is basking in the success of his latest film "Kai Po Che!, " says it is important for actors like him, with no backing in the industry, to be extra careful before signing a project.

"If we don't give a thought before signing a film, there is no point. We have to do numbered films - you might do 100 or 200, but they should be such that people say, 'He has done 50 films, but all are fantastic', " the 28-year-old said here Friday at the Lavasa Women's Drive Awards Ceremony.

"Also, if we don't think before signing a film, we will soon be out of the industry because we do not have any other kind of support here, " he added.

Raj Kumar has earlier featured in films like "Love, Sex Aur Dhokha", "Ragini MMS" and "Shaitan".

He admits "there should be a good story, good character which challenges me as an actor".

"I should get something to explore in a character, " he said about his choice of roles.

Raj Kumar will next be seen in "Shahid", w hich had itss world premiere at the 2012 Toronto International Film Festival's 'City to City' programme.

The film is slated to release in India this year. The actor says it's a very inspirational film. "'Shahid' is a biopic. Its about this lawyer Shahid Azmi who was shot dead in Mumbai in 2010. It is his story. It's an inspirational film, hard-hitting but factual, " he said.
