Mike Tyson,the former heavyweight boxing champion,once notorious for his bad boy antics,has a new goal: hed like to dance and act in musicals. Ive always been a bad guy who wanted to be a good guy, said Tyson,46,on the sidelines of the CLSA Investor Forum in Hong Kong last week. The convicted rapist who spent three years in prison,spoke about his life before and after boxing and his acting career,which includes a recent one-man show on Broadway. Britney Spears showed off her mean streak as the new talent judge on The X Factor,but the TV singing contest stumbled with American viewers,drawing a smaller audience than last year and getting drowned out by The Voice and America's Got Talent. Spears,the 30-year-old pop star impressed critics and fans with cutting remarks and a no-nonsense dismissal of bad contestants. Al Pacino,the Godfather star may soon be portraying the late Penn State head football coach Joe Paterno in a possible film or TV project that is currently being shopped around Hollywood. Hollywood industry website Deadline.com reported that Pacino has expressed an interest in playing Paterno,who fell from grace in a pedophile scandal that rocked the United States last year. The film would be based on the best-selling biography Paterno.
