Larry Hagman, Linda Gray, and Patrick Duffy

 Larry Hagman, Linda Gray, and Patrick Duffy, who portrayed J.R., Sue Ellen, and Bobby Ewing on Dallas, developed deep, lifelong friendships from their first script reading and early filming days in a modest Texas motel, where Hagman supplied champagne for celebrations. Gray recalled instant chemistry, having crushes on both men from prior roles like Hagman's Major Nelson and Duffy's Man from Atlantis, leading to off-screen laughter that contrasted their on-screen tensions. Duffy and Hagman bonded immediately as best friends until Hagman's 2012 death, while Gray and Duffy continued reuniting for tributes, interviews, and the 2012 reboot, highlighting their enduring camaraderie.
