LONDON (AP) Cowboys, stetsons, bucking broncos and J.R. masks it could only be the arrival of "Dallas" in London.

Stars Larry Hagman, Linda Gray and Patrick Duffy were at a Southfork Ranch outpost by the River Thames on Tuesday night to launch the rebooted soap with a big Texan party.

The younger generation of actors Jesse Metcalfe, Josh Henderson, Jordana Brewster and Julie Gonzalo also was there.

After success in the U.S., the first season of the new "Dallas" TV series will be shown in the U.K. beginning Sept. 5 on Channel 5.

Duffy, who plays Bobby Ewing, says it was British audiences who helped the show become a hit the first time around, when they adopted the night-time soap and made it popular around the world.

He's hoping they'll do the same with the re-launched version.
