Not really an Oscar winning interpretation the one George Clooney gave during the press conference for the presentation of Michael Clayton movie at the 64th Venice Film Festival.

From imdb plot summary:

Michael Clayton (George Clooney) is an in-house "fixer" at one of the largest corporate law firms in New York. A former criminal prosecutor, Clayton takes care of Kenner, Bach & Ledeen's dirtiest work at the behest of the firm's co-founder Marty Bach (Sydney Pollack).

When asked by a journalist how he thought was possible to believe in a role like the one he's playing in the movie, and how to keep coherent when talking about bringing back that kind of American cinema tradition of social investigation and denunciation with his payed role as testimonial for such a controversial multinational company as Nestlé, mr. George Clooney found nothing better than first denying he was a Nestlé testimonial, then stuttering something and closing the microphone.

You can see the video here (the Journalist question is in Italian, Clooney's stuttering in, ehm, plain English).

The question transcription is the following:

Considering the role you are playing in this movie, that is a lawyer that goes against a dirty playing multinational company, and I think you are quite on tune with this character since you accepted the role, what I want to know is: how do you coherently manage your role as a advertisement testimonial for Nespresso, a Nestlé brand, that is one of the most boycotted company in the whole world?

Do you think your real life and your fictional one are in some terms colliding because of this role you played [in Michael Clayton]?

In these times when you just need to be a public person, with a lot of money, to automatically become a humanitarian icon, while children shopping in Africa or Asia like you were in a supermarket, someone with the guts to make his job, and ask questions not previously decided with the film production is the real star.

The movie is produced by Section Eight, the production company founded by George Clooney and Steven Soderbergh.

A production company founded by George Clooney and Steven Soderbergh. Section Eight is a US military term, meaning a discharge for physical or mental unfitness from service.
