Might sound stupid - but has he ever played the underdog?
In every single film or TV show I've seen him in, Willis is always playing the badass, the alpha male, the calm collected yet vibratious working class hard nut.
Don't know the guy in real life at all, but all vids & interviews show a similar sort of man, albeit more quiet and thoughtful.
When actors break away from their usual type, the performance tends to be one of their best, or at least one of the most memorable. Henry Fonda did it in Once Upon A Time In America; Heath Ledger did it with The Dark Knight; Lance Henriksen did it with Aliens; and I'd argue Jack Nicholson did it with About Schmidt.
So I'd like to ask, has there been any notable performances whereby he has played a very different sort of character to his usual?
