Casting coups in Bollywood
Silsila, 1981
The relationship between Rekha and Amitabh Bachchan was the hottest Bollywood topic then.
And in Silsila, Amitabh is in love with Rekha, but has to marry his brother's pregnant fiancee Jaya Bachchan when his brother Shashi Kapoor dies in a plane crash.
Rekha marries Sanjeev Kumar.
But the romance between Amitabh and Rekha continues as they continue seeing each other, despite being married.
The film -- for which reportedly Yash Chopra changed the cast at the last minute -- was way ahead of its time, and failed to click with the audiences.
