Harvey Dent speaks to Gotham Tonight

And one full new minute of Joker action...

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.
