Gehraiyaan, starring Deepika Padukone, Ananya Panday, Siddhant Chaturvedi, Dhairya Karwa, Naseeruddin Shah and Rajat Kapur, directed by Shakun Batra and produced by Karan Johar, dropped its trailer on Thursday, 20th January, and it looks like a matured, layered, complex love story, revolving around infidelity and adult relationships, diving into the depths of convoluted modern ties, letting go and taking control of one's own path. Speaking of complex love stories, Gehraiyaan got us thinking about other similar Bollywood movies involving love triangles, revolving around infidelity or not, matured or light-hearted, and which among them struck gold at the box office.

(Note: Only those movies with love triangles as the central theme have been considered, which is why films like Hum Aapke Hain Koun and Kya Kehna haven't been considered. Also, movies where the third party is an obsessive lover, such as in Darr and Agni Sakshi, have been left out.)

It's evident from above that Shah Rukh Khan is the undisputed King of love triangles with as many as seven successful entries on the list, after leaving out the likes of Darr and Anjaam. Amitabh Bachchan, Anil Kapoor and Salman Khan together come in at a distant second with three such commercially successful films each.
