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.
