Sasurbari Zindabad (English: Three Cheers for the In-laws) is a 2000 Indian Bengali-language masala film co-written and directed by Haranath Chakraborty.

On the day of the wedding, just when Rupa had given up all hope, Somu makes a dramatic entry to take charge of his ‘sasurbari’ (in-laws’ house).

All lyrics are written by Gautam Sushmit; all music is composed by Babul BoseSasurbari Zindabad created box office history by becoming the first Bengali film to cross the ₹2 crore mark in West Bengal.

Made on a large budget of ₹60–70 lakh,[1][2] the film's final box office collections reached a staggering ₹2.50 crore;[3] thus fulfilling all criteria to be adjudged an ‘All-Time Blockbuster’.

In the process, it went past previous Prosenjit-Rituparna blockbusters like Sudhu Ekbar Bolo, Baba Keno Chakor and Moner Manush, to become the highest grosser ever.

[6] Sasurbari Zindabad introduced a number of new trends in Bengali cinema which were attributed as the main factors behind the film's smashing performance.

A substantial amount of this budget was spent on improved picture quality, technology, grandeur, sets, costumes, and shooting locales, which increased the attractiveness of the film.

[5] Kaushik Sarkar, art director of Shah Rukh Khan starrer Yes Boss was roped in to do the production designing of this film.

[9] Before this, the only other film for which the incredibly popular pair of Prosenjit and Rituparna locked lips (in multiple sequences) was Rituparno Ghosh’s cult-classic Utsab, which had its festival premiere just 3 weeks earlier.
