It's become a tradition at various fan-driven conventions for celebrities to geek out amid their biggest fans without their fans actually knowing they're right next to them.

A convention where fans cosplay in different costumes affords anyone the luxury to throw on a mask and mingle, and the latest to make the attempt was perhaps the most talked-about gentleman at this year's Star Wars Celebration: Alden Ehrenreich, the new Han Solo.

Here's what it looked like when he donned a stormtrooper helmet and took to the convention floor amidst a ton of unsuspecting fans.

While we received no confirmation as to whether Ehrenreich will make a cameo appearance as Han Solo in the upcoming Rogue One: A Star Wars Story, we now know he'll begin filming Solo's untitled stand-alone movie early next year, with its directors, Phil Lord and Chris Miller, now living in London as they prep for production.

Amusingly, though they auditioned tons of dudes for Han Solo, Ehrenreich was actually the first person to audition. While onstage, they revealed that he also screen-tested inside the Millennium Falcon with Chewbacca. "It was the coolest part of the audition — it was pretty unbelievable," Ehrenreich said. "I never auditioned next to a wookiee before. It was pretty awesome."

As an aside, if Ehrenreich did film a cameo in Rogue One, he likely did so within the last month during the film's reshoots. That means the way he looks in these pics might just be what he's going to look like as Solo, perhaps with some slight changes to his hair.

So basically, he'll most likely look something like this. 

And speaking of Rogue One, it was revealed at Star Wars Celebration that it probably won't feature an opening crawl. Lucasfilm's Kathleen Kennedy told ET that they probably won't include one, which is why they teased that fact during the Rogue One panel by opening with the crawl from A New Hope and then interrupting it in the middle before cutting it completely.

Director Gareth Edwards followed Kennedy by adding that these films are supposed to be different from the Episode films. "This film is born out of a crawl. The thing that inspired this movie was a crawl and what was written in that," he said. "There's this feeling that if we did a crawl, then it'll create another movie. And so the honest answer is you'll have to wait and see."

We don't have to wait long! Rogue One: A Star Wars Story hits theaters on December 16.
