Actress Preity Zinta, who gears up for the release of "Ishkq In Paris", feels shooting for her first production venture has been the most difficult job so far. "Till now I considered 'Lakshya' my toughest film but after shooting for 'Ishkq In Paris', I realised that the latter has taken over that tag," said Preity, who made her acting debut with 1998 film "Dil Se..."

Directed by Farhan Akhtar, 2004 film "Lakshya" saw the 37-year-old actress as a journalist, who goes to Kargil as a war reporter. "I went 18,000 feet above sea level for 'Lakshya' and I used to get blue on my face and for 'Ishkq In Paris' when we began to shoot, it started snowing in Paris. All this made me realise that nothing comes easy in life, one has to work hard for it," Preity said. Directed by Prem Raj, "Ishkq In Paris" sees the actress in lead role after "Heroes" in 2008. The film also features French actress Isabelle Adjani and debutant Rhehan Malliek.
