Harvey Dent speaks to Gotham Tonight

It's the final week of The Dark Knight promotional push (as it's released Stateside this Friday) so expect a few surprises along the way.

Case in point, Gotham Tonight has its biggest studio guest this week , Harvey Dent (or, depending on how able you are to suspend your disbelief, Aaron Eckhart in character).

And a full minute of footage from the flick has gone online - via MTV - featuring Joker playing with a wonderful toy of his own - a bazooka.

Youtube has them both, click above to see them.
