Zain Durrani, an actor who debuted in 2018, has spoken about his "fantastic" experience working with Akshay Kumar in the film Bell Bottom. Durrani played a role as a "deadly terrorist" in the film.

Bell Bottom, released in 2021, is a spy thriller inspired by true events, specifically the hijacking incidents that occurred in India in the 1980s. The film revolves around a RAW agent, codenamed Bell Bottom (played by Akshay Kumar), who is tasked with rescuing 210 hostages after an Indian plane is hijacked. The film is set in the late 1970s and early 1980s.

Durrani has said that he focuses on being fully present and authentic in each scene, rather than overthinking his performance. He was also seen in the acclaimed 2022 series Mukhbir - The Story of a Spy, where he played the lead as Harfan Bukhari. Zain has expressed that finding his own genuine signature and style as an artist helps him draw attention and quench his artistic thirst.

Akshay Kumar's portrayal of Bell Bottom is that of a suave and calm agent. Kumar's composure makes Anshul Malhotra a very dependable character. The film showcases Bell Bottom as a polyglot proficient in German, Hindi, English, and French.

Bell Bottom received mixed reviews, with some praising the fast-paced, emotion-bound thriller elements and Akshay Kumar's performance. Others found the first half dull and the romantic chemistry between Akshay Kumar and Vaani Kapoor unconvincing. Despite the mixed reception, Durrani's portrayal of the antagonist was noted positively. Some found Durrani impressive in his small role, with nuanced and perfect diction.
