Which of these franchises do you prefer?
William Shatner has shot down all hopes for a peace deal between Star Wars and Star Trek fans.
Fellow Star Trek actor George Takei had called last month for devotees of both franchises to unite against the mutual threat to all science fiction: Twilight.
But now his superior, Shatner who played Captain James T. Kirk in the original Star Trek series, has hammered down on his Lieutenant's quest to broker a peace in the decade-long feud between Trekkis and Star Wars devotees.
"George, уοu're the biggest hazard to calmness and peacefulness," Shatner responded in a video message.
"You've carried on an argument for all these years. You can't just disintegrate in a matter of words. Retribution must be paid, George. We need retribution."
Since the Millenium Falcon first arrived on movie screen in 1977, Star Wars fans and supporters of Cpt Kirk and his crew on the USS Enterprise have exchanged bitter words, as to which franchise was the superior one.
Takei who played Lieutenant Hikaru Sulu, the helmsman of the USS Enterprise had stepped up to demand a ceasefire in the face of a mutual foe: The Twilight franchise.
"Fellow star folks. Cool it down, and shut your big worm holes," said Takei in a video message posted online following the outbreak of a war of words between William Shatner, who played Captain James T Kirk in the original Star Trek Series, and Carrie Fisher, who played Princess Leia in the original Star Wars trilogy.
The feud started when Shatner, who claimed that Star Wars was derivative of Star Trek, prompting Fisher to fire back, calling him to a "costume-off", with her appearing in the metal bikini she wore in Return of the Jedi.
"And my space buns - they're so much better than [Leonard] Nimoy's ears," she added.
Before the intergalactic argument would claim any victims, Lieutenant Sulu rushed in to broker peace.
"What is needed today now more than ever is star peace, for there is an ominous mutual threat to all science fiction," the 74-year-old said.
"It's called Twilight, and it is really, really bad."
"Let us band together to combat this mutual threat," he urged.
Shatner didn't elaborate how Star Trek's retribution should be carried out. But Star Wars universe be prepared: Shatner may be out to whack some Wookies or phaser off Princess Leia's space buns.
