"I am going to show Kakaji's (Rajesh Khanna's) last film to his family members first. It's worth a watch and I am sure they will love the film. I'm planning to show his last film to his family members including Dimple Kapadia, Akshay Kumar, Twinkle Khanna and Rinki Khanna," Tyagi told IANS.
The film is in its post-production stage as of now, and Rajesh Khanna features in a prominent role in it.
"I will send Kakaji's family members an official invitation for an exclusive trial show of his last film. I also want the press to watch the film before it hits the theatres. I am quite confident about this film," said Tyagi, who has decided to release the movie Dec 28, a day before the actor's 70th birth anniversary.
Rajesh Khanna died in July after prolonged illness and a liver infection, and he had wrapped up most of the shooting for "Riyasat".
Ashok says the promotions of the film will start from December itself.
"I don't want to hurry up just to meet the deadline. I am going to do my best. Since its Kakaji's last film, I don't want to keep any stone unturned and want to make this film a memorable one," he said.
