Guest iin London (2017) is a Hindi-language comedy-drama that serves as a spiritual successor to the 2010 hit Atithi Tum Kab Jaoge? . Starring Kartik Aaryan and Kriti Kharbanda , the film follows a young couple in London whose lives are disrupted when uninvited guests, played by Paresh Rawal and Tanvi Azmi, arrive from India.

Upon its release, the film received mixed to negative reviews from critics.

While starting as a comedy, the movie eventually shifts into a more emotional tone, revealing the true reason for the guests' visit—a connection to the 9/11 attacks in NYC.
