Ali plays himself impressively in this biography of his remarkable boxing career. The greatest commands the screen alongside such actors as Robert Duval, Ernest Borgnine and James Earl Jones. The film is not as powerful, moving or exciting as it could have been and so is a slightly disappointing dramatization of a legendary boxing story. But, of course, just to see Ali doing what he does best (entertaining out of the ring as well as in) is a must for most. So, see it.
