For months, fans have been wondering what the official title of STR 51 will be. The working title has always been a placeholder: the film was announced as a fantasy commercial entertainer with Simbu playing a character called “God of Love”, but the actual title has remained a closely guarded secret. Ashwath’s confirmation that it starts with “I” instantly got fans guessing. Names ranging from mythological references to puns on love and identity are already circulating online.

It is worth noting that Ashwath Marimuthu had previously clarified that “God of Love” is not the title, but rather a description of Simbu’s character. It looks like the actual title will be something quite different, and now fans have their first concrete clue.

The other key takeaway from Ashwath’s birthday message is the confirmation that STR 51 will begin principal photography only after Simbu wraps up Arasan, the gangster action film directed by Vetrimaaran and set in Vada. Chennai universe. This was widely expected, but hearing it directly from the director brings the timeline into focus.
