Director Vikram Bhatt denied rumours that his forthcoming film "Speed" was inspired by Hollywood flick "Cellular".

"Producer Harry Baweja came up with the script and I loved the idea. We have changed the screenplay and our film is very original. 'Speed' is an action thriller. There's a twist every two-three minutes in the film and it is completely unpredictable," said Bhatt.

The film has a colossal star cast comprising of Urmila Matondkar, Zayed Khan, Aftab Shivdasani, Sanjay Suri, Amrita Arora, Sophie Chaudhary and Ashish Chaudhary.

Bhatt's film "Red" also stars Amrita and Aftab.

"It ('Red') is a suspense thriller, a dark and emotional love story involving red emotions, red anger, everything dealing with 'red' basically," he said.
