The film, which released on May 8 across 1,300 screens in India and in around 200 screens globally, features megastar Amitabh Bachchan, Deepika Padukone and Irrfan Khan.
"Piku" raked in Rs.5.32 crore on Friday, and witnessed a phenomenal growth via positive word-of-mouth on Saturday with Rs.8.70 crore and Rs.11.20 crore on Sunday -- taking its combined total to Rs.25.22 crore in its opening weekend, according to trade analyst Taran Adarsh.
"Take a bow, Team #Piku... Just look at the REMARKABLE growth in the biz of #Piku. Proves yet again CONTENT is KING," Adarsh tweeted on Monday.
The viewership of the film -- which has 'Motion Se Hi Emotion' as its tagline -- is only poised towards growth, say other industry members.
"The response has been superb till now," Deepak Sharma, chief operating officer, PVR Pictures Ltd, told IANS, and added that the movie went houseful over the weekend.
"It took a drastic jump in collection due to the word-of-mouth publicity since Friday. It's too early to decide the future of 'Piku', but I think it will have a long run in cinemas," Sharma added.
Devang Sampat, business head - Strategy, Cinepolis, said the film's "appealing content and word of mouth is sure to attract and sustain the momentum of the weekend".
"It is sure to sustain the footfalls for the weekdays as well. It has registered over 60 percent occupancy on an average over the weekend in all Cinepolis theatres," Sampat added.
Served with dollops of comedy and emotions, "Piku", which stresses on the camaraderie between a father (Amitabh) and daughter (Deepika), has received rave reviews. Even in theatres, it has spread loud cheers and applause by people of all age groups.
As far as the future of "Piku" on the box office is concerned, it will be interesting to see how well the film will do in upcoming weeks where it is likely to face stiff competition from Ranbir Kapoor and Anushka Sharma-starrer period crime drama film "Bombay Velvet", which releases on Friday.
In the week thereafter, there is the much-awaited "Tanu Weds Manu Returns".
