Sridevi and Kamal Haasan in Vaazhvey Maayam

Gangai Amaran’s music, lyrics by Vaali, you might not have seen the film, but you know all the songs.  

With Kamal Haasan, Sridevi and Sripriya leading the cast, the Tamil hit Vaazhvey Maayam was a remake of Premabhishekam. Sridevi reprised her role from the original and worked on both.  

The movie has... good lord, a lot of plot. See the story description on Wikipedia - its as long as Wuthering Heights. 

The film has great SP songs.
