Last year's biggest billionaire gainer is this year's biggest loser: fortune is down $32 billion in the past 12 months as shares in Reliance Communications, Reliance Power and Reliance Capital all crumbled. Got family's interests in telecom, power and financial services following bitter parting with older sibling Mukesh in 2005. Plans to merge his Reliance Communications with South Africa's MTN were scuttled last July after brother Mukesh threatened to sue, claiming he had right of first refusal. Stock down 58% since. Reliance Power bagged 3 mega power projects for a combined 14,000 MW last year. Married to onetime actress Tina, Anil has Hollywood ambitions; Reliance Entertainment is investing $500 million in a new studio venture with Steven Spielberg's DreamWorks; has signed A-list actors George Clooney, Jim Carrey and Julia Roberts to co-produce future films. May soon bury hatchet with brother: siblings played joint hosts at mother's recent 75th-birthday bash.
