Bollywood superstar Salman Khan who has turned script writer with his upcoming dream project Veer says the film has been a stressful experience for him as an actor and writer.

"It was a stressful experience for me. But Veer has shaped up well and I am happy with the final product," Salman told reporters at the music launch of the film. The period flick, set in 1875, is slated for a theatrical release on January 22, 2010.

Salman, who has further toned his body to suit the role, had first conceived the idea of making a movie on the exploits of a Pindari soldier 20 years ago. Speaking about his new co-star Zarine Khan, Salman said Zarine was a brilliant newcomer as she belongs to the new generation.

Director Anil Sharma disapproved comparisons between Zarine and Katrina Kaif. "It is unfair to compare a newcomer with anybody. By doing this you are belittling the efforts and hard work of a young actor," he said.

Music composers Sajid-Wajid have given the music in the film while Oscar-winning lyricist Gulzar has penned the songs.
