Auschwitz concentration camp was a complex of over 40 concentration and extermination camps operated by Nazi Germany in occupied Poland during World War II and the Holocaust.

'Bawaal', which has been directed by acclaimed filmmaker Nitesh Tiwari, has glimpses of World War 2 and the concentration camp.

Talking about what location is the most loved by Janhvi, she said: "I think Amsterdam for me because I fell in love with the city and as a team we spent a lot of time in that city as well but when we were in Poland we actually went to visit Auschwitz, which was a very moving experience."

She added: "It taught us a lot about the gravity of what we were making and speaking about. So that left a long lasting impression on me and Varun both."
