"These young actors have been cast in 'Dangerous Ishq' because we required actors with no image. That's why they have been cast... and they have been very appropriately cast in the film," said Karisma.
"Dangerous Ishq" features model-actor Rajniesh Duggal opposite Karisma. It also features model-actor Ruslaan Mumtaz, who made his debut with the film "Mera Pehla Pehla Pyaar", and Arya Babbar.
Karisma, 37, who is appearing on the big screen after a gap of five years, says the audience, her family and friends led to her returning to films.
"I have a life beyond movies and I have done the film because the audience, media, family and friends, everyone told me to do a film. I am just excited, more than anything, that the audience will get to see me again on the big screen," said Karisma, who took a sabbatical from work post-marriage to Delhi-based businessman Sanjay Kapur in 2003.
Directed by Vikram Bhatt, "Dangerous Ishq" has been shot in 3D and hits theatres Friday. In the movie, Karisma plays a supermodel, who undergoes past-life regression.
