Larry Hagman, Patrick Duffy and Linda Gray only agreed to return to the set of TV drama Dallas if all three wanted a comeback.

Duffy, who has reprised his Bobby Ewing character for the hit revamp - which debuted in America last week (ends15Jun12), admits he would not have returned to TV's Southfork Ranch if his old pals had opted not to sign on.

He says, ""We don't do anything concerning Dallas unless the three of us agree. If one of us would have said, 'No, I can't do it, then the other two would not have done it.

""We're three best friends. Out of all the cast, we're the three that stayed together for the full 35 years.""
