Whenever a new film is about to be released, cast members typically have to face a barrage of promotional work. While there's a good argument that it's part of their job (and the healthy compensation that comes with it), there's no doubt it can likely be a gruelling process as well. 

Cara Delevingne, promoting her new teenage drama Paper Towns, looks like she found that out the hard way - and the frustration was evident during a recent interview for an American morning show, Good Day Sacramento.

The British actress and model had attended an "emotional" premiere the night before the interview, and after a few weeks of promotional efforts she just did not seem in the mood for the perky presenters and their frivolous questions.

Things got off to a bad start when one of the hosts called Cara 'Carla' at the start of the interview, and the actress offered sarcastic, disaffected answers to most of the questions she was asked. A delay between the two studios didn't help matters.

A third host soon joins the questioning, asking Cara why she seemed less than enthusiastic. She admits "it's just you" when the presenters ask if it's only their show in particular making her feel irritable.

The presenters then spend some time making fun of the whole affair after the interview is brought to an awkward close.
