Director and writer Fenar Ahmad has admitted that a real life experience where his own brother got 'into trouble' inspired him to make this film.
Dar Salim took kickboxing lessons in prep for the movie. He was trained by Lars Krusaa, the national coach of Denmark in Kickboxing.
In preparation for his role as Zaid, Dar Salim followed real heart surgeons in their daily routines. He even watched some real life open heart surgery for the research of his role.
