For her breakthrough role as Vaani Batra, actress Aneet Padda auditioned in a yellow dress, mistakenly thinking it was the character's costume. Despite this "disastrous" moment, director Mohit Suri and co-star Ahaan Panday vouched for her, securing her the lead role from hundreds of applicants.
The film was a surprise hit despite not having big names and despite not releasing on a holiday.
Mohit Suri who often made films under uncle Mahesh Bahtt's banner Vishesh Films switched to Yashraj banner to make this film.
The title track Saiyaara topped Spotify's Global Viral 50 chart, a first for an Indian song, surpassing global artists like Justin Bieber and Billie Eilish.
Film became the highest-grossing Indian romantic film at the time of its release.
