"Genius, billionaire, playboy, philanthropist"
With a knowing smirk and a razor-wit delivery, he made the genius inventor utterly believable, flaws and all. You couldn't imagine anyone else delivering those sharp one-liners or conveying the underlying vulnerability beneath the confident facade.
His performance wasn't just about the quips and the tech; it was about the journey of a self-centered individual grappling with responsibility and ultimately sacrificing himself for something greater. He owned that role, defining it for a generation of moviegoers. The swagger, the intelligence, the occasional flash of pain in his eyes – it all combined to create a truly unforgettable character.
