Freddie Roach, the world-famous boxing trainer who owns and operates the famed Wild Card Boxing Club in Hollywood, where he has produced a host of world champions. This intensely personal look at Roach chronicles his life and career against the backdrop of Parkinson's disease, an ailment very likely linked to his own boxing past. "ON FREDDIE ROACH" debuts FRIDAY, JAN. 20 (9:30-10:00 p.m. ET/PT), exclusively on HBO, with other new episodes debuting the subsequent five Fridays at the same time. (Source: HBO)
