"We did extensive research and travelled for six months across places where the story is based," Sappel said. Even though a lot of effort has gone into production design, Sappel wants audience to relate to the story instead of focusing on the sets.
Kunal Kohli's 'Teri Meri Kahaani', featuring Shahid Kapoor and Priyanka Chopra, depicts love stories set in three different time periods 1910, 1960 and 2012. "We had to create all the three eras and ensure that they look authentic. The 1910 era will have Punjab, the 1960 story is set in Mumbai and 2012 in England. We have been authentic and nothing is false. Creating these eras was in a way difficult but the use of VFX made it a bit easier, it really helped us," he said.
"We want the audience to relate to the story and not the background. We want them to get attached to the emotions," he said.
In the past, Sappel has designed sets for Shah Rukh Khan starrer 'Rab Ne Bana Di Jodi', Amitabh Bachchan's 'Bhootnath', Atul Agnihotri's 'Hello' among others. In 'Teri Meri Kahani', the first story is set in Lahore in 1910 where Priyanka plays a Punjabi girl - Aradhana, in love with a Muslim boy Javed, played by Shahid.
In the 1960 story, Shahid plays a struggling music director Govind and Priyanka is a famous actress Rukhsar and they once again fall in love in Mumbai.
In 2012, the couple falls in love again as Radha and Krish in England. "Creating a 1910 era Punjab was in a way easy - we have a temple, mosque, market, a small village, brick houses etc. In 1960 Mumbai, we have shown trams, chawl, guest houses, old studios and old cinema houses. Creating Mumbai took more time. In 2012 one would see modern times with ancient style of architecture," Sappel said. The film is set to release on June 22.
