Jim Rockford and John Belushi Hung Out -- Hippie Style

James Garner, known to a generation of swooning women and jealous men as titular character Bret Maverick from the 1950s western show Maverick and too-cool private investigator Jim Rockford from the 1970s hit show The Rockford Files, has a new tell-all book out today. 

In The Garner Files, the veteran actor, 83, tells all. And then some.

"Something funny happens as you get older," he writes in the first line of the memoir, "You don't hold back so much." If this book is any indication, that's one true statement.

Garner dishes about himself (he's smoked pot for most of his life and did cocaine with John Belushi), and other famous Hollywood he-men. His friend Steve McQueen, for example, was "an insecure poseur and not much of an actor" and tough guy Charles Bronson -- his co-star in 1963's The Great Escape, was evidently "bitter and belligerent."

The tell-all, on shelves now, is getting great reviews. Writes the Los Angeles Times, "Plenty of self-deprecating humor, a general air of live-and-let-live, but when it comes down to it, no pulled punches."

Sounds like a great read.
