The Buckingham Murders collection day 1 early estimates: Kareena's lowest opening ever

The film earned on ₹1.15 crore [Hindi: 70 lakh ; Hinglish: 45 lakh] on day one. On day two, the film earned ₹1.90 crore nett in India in all languages as per early estimates. So far, it has collected ₹3.05 crore. The Buckingham Murders had an overall 15.70% Hindi occupancy on Saturday.

The Hindustan Times review of the film read, "Kareena is the heartbeat of this film. Roughly 20 minutes in, you forget this is the same person who pulled off a constantly yapping Geet in Jab We Met so well, or a money-minded air hostess in her recent flick Crew. Kareena has the right amount of pain and anger, barring that scene where she screams out of frustration. It feels… like a tick on the list of 'Things a Frustrated Mother Has To Do In Every Film’. When things are subtle, like holding back her tears right until the end, they are impactful."

The film, directed by Hansal Mehta, stars Kareena Kapoor, Ash Tandon, Ranveer Brar, and Keith Allen. It marks Kareena’s production debut. The Buckingham Murders is also produced by Ektaa Kapoor and Shobha Kapoor under Balaji Telefilms and TBM Films.
