The 36-year-old "Hamari Adhuri Kahani" star took to micro-blogging site Twitter to thank fans.
"Awarapan is a film that's very close to my heart. Can't believe it's been 8 years! @mohit11481 @shriya1109 @mrinalinisharm #8YearsOfAwarapan," he tweeted.
Shagufta Rafique, who wrote the crime-thriller, said, "Celebrating my most favourite film with you all on Twitter... Congrats team Awarapan.
"The magic of a film that's made with a heart and soul. Thank you Bhatt Saab Vishesh Films, Mohit Suri, Emraan, Mrinalini, Shreya, Shaad and the entire music team."
"Awarapan", directed by Mohit Suri, saw Emraan as a hitman who falls in love with a girl who teaches him to have compassion for others.
