The film was shot across the Mediterranean and they were extensively travelling on the cruise for 5 weeks.
The team of the film bonded on the cruise and even spent time together when they were not shooting.
In fact, while the ship was sailing there was no network connectivity and only once it would anchor at any port would they get connectivity.
So they all spent even more time together as they did not have their phones to go back to.
Even in between breaks and after pack up they would be seen spending time together.
The entire team would be constantly playing games and engaged in some discussion.
The team of Dil Dhadakne Do had a lot of fun together and this camaraderie is visible on screen.
There is great on screen chemistry visible between all the actors.
