So much has been said by and about the unemployed actor, it’s almost as if there’s nothing left to learn about him.

Sheen’s banking on the "almost" part.

Promising "the REAL story," the 45-year-old ex-"Two and a Half Men" star is hitting the road for a month-long, 20-city tour that gets its start Saturday night in Detroit.

Why Detroit?

"Why not," asked publicist Larry Solters, who, like his boss, hasn’t said a lot about the show, other than it will last an hour and a half and feature guests, music and a multimedia presentation. Rapper Snoop Dogg will be there as will guitarist Rob Patterson.

What remains to be seen is whether Sheen — a talented comic actor, but not a stand-up comedian — can sufficiently entertain a live audience for that length of time.

Sheen appeared in a string of memorable 1980s films ranging from the Oliver Stone-directed dramas "Wall Street" and "Platoon" to the timeless comedies "Ferris Bueller’s Day Off" and "Major League." Later in his career, he found small-screen success as the star of the hit sitcoms "Spin City" and "Two and a Half Men."

But in recent years, the actor has increasingly made headlines for his drug use, failed marriages, custody disputes and run-ins with the police.

The wayward star’s behavior finally became too much for Warner Bros. Television, which booted him from "Two and a Half Men" on March 7.

Sheen fired back with a $100 million lawsuit and all-out media assault in which he informed the world about his standing as a "rock star from Mars" and a "warlock" with "Adonis DNA" who lives with two "goddesses" — both of whom he said would be at the Detroit show.

His unique banter and catchphrases — think "winning" — have spread over the Internet and onto T-shirts, more than a few of which are expected to be sold on the tour, which wraps up May 3 in Seattle after stops in Atlanta, Chicago, Dallas, Denver, Houston, New York, San Francisco and others. Sheen has said the Detroit show, where tickets cost $45 to $80, sold out.

"I am bringing ‘My Violent Torpedo of Truth/Defeat is Not an Option’ show out to you in the battlefield," Sheen said in a video announcing the tour. "If you’re winning, I’ll see you there. Trolls need not apply. . . . Buy your ticket. Take the ride. And the ride will take you."

The ride begins in the Motor City where the star of the show will grace the stage of the historic Fox Theatre, which sits across Woodward Avenue from Detroit’s baseball destination, Comerica Park.

It’s probably fitting that Sheen is opening his show within sight of the home of the Tigers.
