Kamal Haasan's career has seen multiple instances of projects being shelved, facing major delays, or undergoing director/cast changes, similar to the situation with Sundar C stepping away from Thalaivar 173.
Robot/Enthiran: Initially planned with Kamal Haasan and director S. Shankar in the early 2000s, the project was shelved due to scheduling conflicts with Haasan. It was later revived with Rajinikanth in the lead.
Marudhanayagam: One of Kamal Haasan's most ambitious historical epics, it was launched with much fanfare in 1997 (with Queen Elizabeth II attending the event) but was shelved due to massive budget issues and lack of consistent funding.
Sabaash Naidu: A spin-off of his Dasavathaaram character, this film, launched in 2016, faced multiple halts due to directorial changes (Kamal Haasan took over direction after the initial director fell ill), financial troubles, and Kamal Haasan's political commitments.
Vishwaroopam: This film saw a major director change when Kamal Haasan took over the reins after Selvaraghavan was initially signed but had to be ousted due to scheduling conflicts.
The film with Mahesh Narayanan (believed to be a sequel to Thevar Magan): This film has been delayed due to Kamal Haasan's busy schedule with Indian 2 and other commitments.
