Aryan (Kartik Aryan), who is on a work visa in the United Kingdom, decides to indulge in a sham marriage with NRI Anaya (Kriti Kharbanda) to get permanent citizenship, but has to contend with an irritating and unwanted guest (Paresh Rawal) and his wife (Tanvi Azmi) to allay the suspicions of a government officer (Sanjay Mishra) investigating the veracity of the marriage.

Aryan (Kartik Aaryan) is looking to get permanent citizenship in the UK and plans to fake-marry his girlfriend Anaya (Kriti Kharbanda) to get this done. At the same time, Chacha (Paresh Rawal) and Chachi (Tanvi Azmi) arrive in London to visit their faraway relative, which happens to be the hapless Aryan. Like Athithi Tum Kab Jaoge, the guests irritate the hosts with their super-intrusive ways. However, Aryan needs them to validate his fake marriage, so has to bear with them. But how much patience can someone have before they reach their tipping point? That's the question Aryan, or for the matter, the audience has to ask themselves.

Aryan and his British Indian girlfriend Anaya is planning to fake a marriage so that he can get a citizenship in the UK. 10 days before the wedding, Aryan's distant uncle's (who stays in India) neighbour's tenant Gagga chacha and Guddi chachi suddenly land in Aryan's office. A reluctant Aryan has to take them home. However, although Aryan and Anaya are not the ones who believe in Atithi Devo Bhava, they need this elderly couple as witnesses of their (fake) marriage as their only relative in London. So, they decide tolerate this interfering, quirky, irritating but loving and caring chacha-chachi until they completely lose their patience.

Guest Iin London goes against everything the movie industry has been trying to accomplish in the recent past. It spends 2 hours and 18 minutes hitting CTRL+Z on the kind of experimental storytelling, fresh writing and gender balance that the industry has been striving towards. Instead, it gives us men talking down to women, nonchalant racism, forced gay humour and a buttload of fart jokes. So much so that Paresh Rawal's character recites a minutes-long "ghazal" about farts. The movie covers toilet humour extensively from poop and pee jokes, right up to kidney stones.

Do you find an unending series of fart jokes, accompanied by loud sound and smell, and descriptions thereof, funny? Do cheap racist shots (blackface, mehendi-orange-beard and green-for-Muslim, slant-eyed-for-Chinese) make you laugh out loud? Do you think crude jokes should be strewn liberally in your weekly flick fix? Should a gag, abysmally executed in the first place, be stretched out like a rubber band to keep you rolling in the aisles? These are elements that 'Guest Iin London', a follow-up to 'Atithi Tum Kab Jaoge', has in abundance. It also has a couple of vacuous younger leads saddled with a middle-aged couple which refuses to leave : Paresh Rawal being the proud possessor of a noisome rear end, and Tanvi Azmi, the only one I feel for, trying to make the best of a terrible job.

More than the sequel, Guest Iin London is a copy of 2010 film Atithi Tum Kab Jaoge? by the same director. Just that this time the action has shifted from Mumbai to London. You won't find actors like Ajay Devgn and Konkona Sensharma in the new film, but Paresh Rawal, as the nerve-wrecking guest, tries to fill for the missing big names. One more thing, what seemed like a fine balance of comedy and slice of life in the original is completely absent here. In fact, it's so lame that you would find the tobacco ads more entertaining than watching Paresh Rawal farting for at least hundred times.

Which was the last comedy Bollywood made? While opinion can be divided on that, one doesn't remember having seen a laugh riot as good as Hera Pheri. Just like its sequel Phir Hera Pheri disappointed big time, the kabhi haan, kabhi na sequel to Atithi Tum Kab Jaoge, Guest Iin London (the film's actors and director disagree that it is a sequel to the Ajay Devgn-Paresh Rawal 2010 movie, but critics differ) also fails miserably.
