Looks like Ram Gopal Varma can't stop raving about Sridevi after watching the trailer of the yesteryear heroine's comeback venture 'English Vinglish'.

"Watched 'English Vinglish' trailer. After 15 year hiatus, Sridevi is looking 15 times more beautiful and seems to have become 15 times better actress," wrote the ace director on his microblogging page.

'English Vinglish', which marks the directorial debut of Gauri Shinde (wife of popular filmmaker Balki), is being made in Hindi and Tamil, simultaneously.

The Tamil version has a guest appearance by Ajith. The cameo was done in the Hindi version by Amitabh Bachchan.

The movie will be premiered at Toronto International Film Festival this year which is going to be held from September 6-16.

It is a story of a woman’s struggle with the English language and the insecurities she faces because of it. The film shot mostly in New York captures her transformational journey.
