8 September 2013, Karan Johar told IANS, ""Koffee With Karan" will be on air in December. I will start shooting for it in December". Later that month, Salman Khan was confirmed to make his debut in the season premiere which aired on 1 December 2013. The premiere also saw the appearance of Khan's father, veteran screenwriter Salim Khan, who joined him halfway through in the episode. Along with Khan, many other established Bollywood celebrities appeared for the first time this season. They include Aamir Khan, Kiran Rao, Akshay Kumar, Emraan Hashmi, Mahesh Bhatt, Anurag Kashyap, Juhi Chawla, and Rohit Shetty. While the show has retained its 9 PM Sunday slot since the second season, the 14th episode of season 4, featuring India-born Hollywood actress Freida Pinto and Nargis Fakhri, was moved to the 11 PM slot reportedly due to the channel's view that the content "was too bold for prime time viewing". Several celebrities who were regulars in the past, including Rani Mukerji, Hrithik Roshan, Saif Ali Khan, Sanjay Dutt, Ekta Kapoor, John Abraham, and Lara Dutta, did not appear in season 4 with the most notable absence being that of Shah Rukh Khan. Both Khan and Saif Ali Khan have since appeared on the show in the following season.
