Lena Dunham takes a tumble in the first promo for the fourth season of Girls.

The brief clip sees Dunham's character Hannah Horvath on a bicycle, but her journey is interrupted by a stumble that sees her tumbling to the ground with a shriek.

A twist at the end reveals a tongue-in-cheek nod to the upcoming return of the award-winning comedy-drama series.

The cast will be bolstered in the new season by appearances from guests Spike Jonze, Maude Apatow and Gillian Jacobs.


Girls is due to return to HBO in early 2015.
