Tom Hanks

Despite being a two-time Academy Award winner, Hanks still sometimes thinks of himself as a "fraud" stealing a living in Hollywood.

He told NPR in 2016: "No matter what we've done, there comes a point where you think, 'How did I get here? When are they going to discover that I am, in fact, a fraud and take everything away from me?' There are days when I know that three o'clock tomorrow afternoon I am going to have to deliver some degree of emotional goods, and if I can't do it, that means I'm going to have to fake it. If I fake it, that means they might catch me at faking it, and if they catch me at faking it, well, then it's just doomsday."
