In this case, the actress signed Vikram's 'Saamy 2' under Hari direction and she said it was glad to be back to the movie which gave her the identity a decade back. But all of a sudden, she walked out of the movie and she wished the team 'Good Luck!'. However, the Producer complained to the Producer council and it was expected that she would face a Red card.
There were reports that Trisha walked out of the movie as Keerthi Suresh gets more screen space than her. In this case, Trisha has explained why she walked out of the movie to the Producers Council. She has said, "I never acted even one scene in the movie. So I have the legal rights to walk out of the project. I will return the advance which I got from the producer. I am signing out due to personal reasons."
Now, even though Trisha has made it clear she is out, the makers are still trying to bring her back inside the movie to have the continuity from the predecessor. So, as for now, the in-and-out game continues with Trisha in 'Saamy 2'.
