Directed and co-produced by Farah's husband Shirish Kunder, 'Joker' had Akshay Kumar and Sonakshi Sinha in the lead but Akshay did not promote the film amid reports that he had differences with Kunder.
"'Joker' got a bad response. People had killed the film even before it released. What happened was not nice, lesson learnt - go ahead. When a star does not stand by the film then it is free for all...That is all I want to say," Farah told PTI, without naming anybody.
"You have to stand by the film, that is very important. So you will have to work with those who will stand by the film, come what may," she said.
On if her statement implies that she would not work with 'Joker' lead actors in future, Farah said, "I am not saying anything now, we will talk about 'India's Got Talent' (the show that she is part of right now)."
Meanwhile, Farah is ecstatic that her debut film as an actress 'Shirin Farhad Ki Toh Nikal Padi' got good response at the box office.
"I think the film did pretty well. When I saw the film I had thought it is a nice movie and that people will like it. I knew it is not going to be a blockbuster or a Rs 100 crore film. It had Boman Irani and me, so the kind of response we have got I am pretty much happy about it," Farah said.
"I am happy to have got good response for my performance and also my first debut actress award -- the Kalakar Sangeet award from Kolkata," she said.

Meanwhile, she has taken to judging reality show 'India's Got Talent'.
"The best part about 'India's Got Talent' is that we get to see different kinds of talent," Farah said.
Farah also revealed that she regularly follows reality show 'Bigg Boss' as she likes to see all that happens in the house. "I like 'Bigg Boss' and follow it regularly," she said.
