These on-screen brother-sister pairs bare no resemblance to each other - we need a filmy DNA test to prove they've got the same genes! Hrithik Roshan looked more like Kanika Tiwari's dad in 'Agneepath' (2012).
You could look from any angle, but Aishwarya Rai Bachchan and Shah Rukh Khan in 'Josh' (2000) look nothing like real siblings.
This is too much! Salman Khan, Saif Ali Khan, Mohnish Behl and Neelam in 'Hum Saath Saath Hain' all look like they're from different continents.
Not only do Juhi Chawla and Samir Soni look different, we still pictured them as husband-wife as in 'Jhankar Beats' from 2003 when they reunited as siblings in 'My Brother Nikhil' in 2005.
In 'Pyar Kiya Tho Darna Kya' (1998), wasn't it weird that Kajol's brother and boyfriend look so alike? Oh wait, because they are brothers in real life!
Tusshar Kapoor and Kareena Kapoor, seen here in 'Golmaal Returns' have nothing in common except their last names. But then they would top our list of the most unlikely romantic pair too.
Genelia D'Souza and Prateik Babbar looked more like sister-sister in 'Jaane Tu... Ya Jaane Na' (2008).
Prachi Desai and Ajay Devgn in 'Bol Bachchan' (2012) couldn't be more dissimilar.
Sanjay Dutt, Abhishek Bachchan and Diya Mirza as siblings in 'Dus' (2005) left us as flummoxed as the film!
