Carl’s Jr. has done just about everything it possibly could to get a “SpielBurger” in Steven Spielberg’s mouth.

On Sunday, the U.S. burger chain announced it was changing the name of its charbroiled sliders to “#SpielBurgers” in honour of the filmmaker’s new movie “Ready Player One”.

Carl’s Jr. confessed it did not have Spielberg’s permission to rebrand its burger, but it was convinced the famous director would get on board.

What came next was a two-day campaign dedicated to having Spielberg sign off on its new creation. “Sure hope he’s cool with it,” tweeted the Carl’s Jr. Twitter account. “We pretty much spent our whole marketing budget on #SpielBurgers.” They realized soonafter, however, the “Jaws” genius does not have Twitter.

Hmmm, no word from Spielberg yet. Sure hope he’s cool with it. We pretty much spent our whole marketing budget on #SpielBurgers — Carl's Jr. (@CarlsJr) March 26, 2018

You guys, we just realized STEVEN SPIELBERG ISN’T ON TWITTER. Anybody got his digits? #SpielBurgers — Carl's Jr. (@CarlsJr) March 26, 2018

And so the burger chain took its “Ready Player One”-themed burgers to the film’s red carpet but only managed to get Spielberg to wave from a distance.

Undeterred, Carl’s Jr. journeyed to Spielberg’s office at Amblin Entertainment to deliver the burgers in person.

Unfortunately, security was not sold.

Welp. Just got booted from @AmblinEnt. Obvi must have been some sort of misunderstanding. Bummer! #SpielBurgers pic.twitter.com/D2gr0xaOpy — Carl's Jr. (@CarlsJr) March 27, 2018

But either word or the smell of savoury “SpielBurgers” reached the filmmaker as Spielberg, 71, later recorded a video from the absurdly long hallway of his home and kindly turned down the burger chain’s offer.

“Carl’s Jr. wants to rename their charbroiled sliders ‘SpielBurgers’, and they’re pretty good but I’m passing,” said the director. “Cease and desist, you can’t do it. Sorry guys.”

Carl’s Jr. was not too disappointed. It was just happy Spielberg enjoyed its burgers.

“Ready Player One” premiered at South by Southwest and hits theatres on March 29.
