Martin Garbus's client list reads like a Who's Who of authors, actors and playwrights. It also includes Miramax and Bloomberg, L.P. and Nelson Mandela.
The legendary First Amendment advocate made a name for himself when he defended Lenny Bruce against obscenity charges. He later continued the theme in representing Don Imus.
Garbus's decades-long career is full of celebrity and athlete highlights. He once went after a cigarette maker on behalf of Robert Redford (pdf) and represented Barry Bonds' ex-girlfriendwhen the FBI allegedly tried to discourage her from speaking to Senator George Mitchell.
Celebrity clients: Michael Jackson, Winona Ryder, Chris Brown and Scott Peterson
Mark Geragos might be the most "famous" of the celebrity attorneys, at least if measured by how often we see him in the news.
Geragos was hired then fired by Michael Jackson to defend him against molestation charges, but Geragos still testified on behalf of Jackson at trial. He also defended Winona Ryder in the case where she was convicted of shoplifting from Saks.
A media storm erupted earlier this year when pictures of battered pop star Rihanna were released; the culprit was Chris Brown, who immediately hired Geragos. Geragos made news by telling CNN that Brown had learned his lesson.
