Floyd Mayweather

Ding ding!  It's on!  Floyd Mayweather Jr.’s attempt to match late heavyweight champion Rocky Marciano's 49-0 record at retirement will come against former welterweight world champion Andre Berto Sept. 12 at MGM Grand in Las Vegas.

When actors transform for a role, we take notice (and most of the time, so does that little golden statue named Oscar). Christian Bale in ‘The Machinist,’ Matthew McConaughey in ‘Dallas Buyers Club,’ Charlize Theron in ‘Monster,’ Christian Bale in the ‘Dark Knight’ trilogy, etc. Jake Gyllenhaal recently joined the club when he dropped 25 pounds to play the sociopathic Lou Bloom in ‘Nightcrawler,’ and now he’s at it again with his incredible transformation for his next film, Antoine Fuqua’s ‘Southpaw.’
