Actress-turned-writer Twinkle Khanna has slammed veteran actor Naseeruddin Shah for calling her late father and Bollywood superstar Rajesh Khanna a "poor actor".

In an interview to a newspaper, Naseeruddin was quoted as saying: "It was the 1970s when mediocrity came in Hindi films. That's when the actor called Rajesh Khanna joined the industry. For all his success, I think Mr. Khanna was a very limited actor. In fact, he was a poor actor. Intellectually, he wasn't the most alert person I have ever met. His taste ruled the industry."

Not happy with the 65-year-old star's opinion about her late father, Twinkle took to Twitter on Saturday night to express her disapproval.

"Sir if you can't respect the living, respect the dead -- mediocrity is attacking a man who can't respond Naseerudin Shah," Twinkle wrote. 

Rajesh Khanna, who made his debut in 1966 with "Aakhri Khat", gave several hits like "Anand", "Haathi Mere Saathi", "Kati Patang", "Bawarchi" and "Aradhana". He was officially bestowed with the title The First Superstar of Indian cinema at Dadasaheb Phalke Academy Awards in 2005.
