Kelsey Grammer, who will play the title role in "Macbeth" this summer on Broadway, says he is returning to the stage partly because of a heightened sense of mortality.

The 45-year-old star of the sitcom "Frasier" says the untimely deaths of his father and sister made him more aware of how short life is.

"I will always be foolhardy because, to me, the best fruit of life is the idea that you don't always play it safe. If you don't reach beyond where you're comfortable, you will not grow," he told TV Guide.

He also says he's expecting some tough reviews from New York drama critics.

"I haven't had this much fun since I rolled my car," he says, referring to the 1996 wreck that nearly killed him and sent him into drug rehab.
