When the film was launched, the title was "Actress". After much thought, Mukesh Bhatt decided to call the film "Awaarapan". Finally, they settled on "Woh Lahme".
During the early stages of casting, Meera was considered for the role of Sana Azim. The film was based on actress Parveen Babi.
The scene where Kangana Ranaut throws her panties on Shiny Ahuja's face at a party was inspired by real-life events of Parveen Babi. Mahesh Bhatt disclosed that after having a few drinks at parties, Parveen Babi would remove her bra and throw it at Mahesh Bhatt, saying it made her uncomfortable.
Title inspired from the hit song Woh Lamhe from Zeher 2005, which was also directed by Mohit Suri.
The last film based on Mahesh Bhatt and Parveen after Arth and Phir Teri Kahaani Yaad Aayi.
