Glengarry Glen Ross

Alec Baldwin, 50: In a way he's come full circle -- Baldwin got his start in Hollywood on TV in the '80s, on shows like "Hotel" and "Knots Landing," before being whisked onto the big screen. He made a big testosterone splash in films like "The Hunt for Red October" and "Glengarry Glen Ross... more" (and still delivers great film performances, as "The Departed" attests), but he's found the role of a lifetime as the venal corporate climber Jack Donaghy on NBC's "30 Rock." "Of course he's in a tux, Lemon -- what do you think he is, a farmer?!"
