The meeting of the two characters will take TV fans of a certain age right back to the 1980s, when the couple's tempestuous relationship dominated the show and had viewers hooked.
Watch the preview clip of JR and Sue-Ellen in series two below:
JR proves that he's lost none of his charm ("You're still the prettiest girl at the ball") and leaves Sue-Ellen a little shaken (and possible wooed) by his compliments.
How long will the pair's relationship remain calm and peaceful? Anyone who watched in the '80s will know that trouble no doubt lies in store just around the corner.
Dallas airs on Wednesdays on Channel 5.
