US TV legend Larry Hagman was constantly drunk on the set of 1980s classic Dallas. The actor, who played JR EWING on the Texan drama, happily shared his alcohol with his castmates, but insists his on-screen brother Patrick Duffy - who played BOBBY - would refuse to touch the booze after finding sobriety. He says, "Yeah, I drank about five bottles of champagne a day. I'd have half a bottle by 9am just to get that 'click' and I just kept it up through the day. "I was never stumbling drunk, I could always remember my lines and I was happy as a lark. We started the day with a laugh and we just carried on. "Of course, I shared it around a bit, but Patrick - Mr Goody Two-Shoes - always stayed completely sober."
