Will Ferrell in new political comedy The Campaign

As America's election season gets set to intensify Hollywood is releasing a new political comedy called The Campaign with stars Will Ferrell and Zach Galifianakis playing competing congressional candidates.

As Talking Movies' Tom Brook reports the film depicts a fictional political landscape rife with negative campaigning that's not that different from what happens in the real world.

Talking Movies is broadcast on BBC World News on Saturday at 1330 GMT and Sunday at 0030, 0730 and 2030 GMT.
