"The journey we have undertaken is emotionally charged and physically strenuous. The story grips me completely," Imtiaz Ali said in a statement.
He is happy with the cast of this romantic drama, which is being shot in real locations across different parts of north India.
After teaming up with Shahid Kapur in Jab We Met, Saif Ali Khan in Love Aaj Kal and Ranbir Kapoor in Rockstar, Imtiaz is enjoying working with Randeep Hooda and Alia Bhatt in his new film.
"Alia is responding beautifully, Randeep is a fantastic actor. I am very excited about the locations we are shooting in and it's very comforting that Sajid Nadiadwala (producer) is standing behind us," he added.
For "Highway", Imtiaz has reunited with Oscar-winning composer A.R. Rahman, who gave a mix of lilting and powerful melodies for the hugely successful musical "Rockstar".
"The grace flowed in as soon as I decided to go on this journey - Rahman sir agreed to join. I feel this movie needs him more than ever before. Then we got the ideal cast - Alia and Randeep, and the ideal crew," said Imtiaz.
A. R. Rahman said: "It's a highway journey this time; with the same good company of Imtiaz and lyricist Irshad Kamil."
Nadiadwala promises the project will be treat for fans of Rahman's music.
"'Highway' will again be an all-new musical experience for fans of A.R. Rahman and who other than Imtiaz Ali to bring them to life on screen. I am delighted to present the film," he said.
