Filmmaker Ram Gopal Varma is excited about teaming up with Amitabh Bachchan once again for "Department", which will see the megastar in an intense role of a gangster-turned-politician.

"Am mighty excited about the role Mr. Bacchan is playing in 'Department' ... he's playing a gangster turned politician. Imagine the 'Agneepath' character turning over a new leaf and yet to have the same hard intensity and been there done that know how," Varma posted on micro-blogging site Twitter.

The two have earlier worked together in "Sarkar", "Sarkar Raj", "Aag" and "Rann". "Department" was also supposed to feature Abhishek Bachchan, but he has now been replaced by southern actor Rana Daggubati.

"I highly respect Mr. Bachchan and am highly affectionate towards Abhishek and the reasons for the changes in 'Department' are nothing but date issues," he added.
