Tom Hanks is a rarity. Movie stars today don't achieve, and then maintain, his level of fame for almost 30 years. There are too many movies these days, too many movie stars, and too many new ways for us to spend our leisure time. Celebrity has become a more diffuse phenomenon. So how has Hanks' profile remained so large for so long? Hanks is often compared to the late actor Jimmy Stewart. Hanks has that same likability, the same everyman quality. But his film career has followed a very different trajectory. Stewart never had the opportunity to work in the variety of film genres that Hanks has explored. Hanks' forays haven't always been successful. His odd performance in the 2004 remake of The Ladykillers, for instance, was painful to witness, and going back further, audiences were turned off by his portrayal of a nasty standup comedian in 1988's Punchline. But the sheer variety of roles evidenced in just his 10 best movies, listed here, makes it abundantly clear how the star has refused to fall back on the qualities that made him a star in the beginning. That's smart, and that more than anything helps explain why Hanks' celebrity has endured. He's worked hard to keep it.
