TMZ just released some BTS photos from the Solo movie, including our first look at Ehrenreich in costume.

Plus, a whole bunch of speeders.
I wonder if we’ll get a bit of an American Graffiti-vibe with young Han doing a lot of racing (which would make sense in an origin story about a pilot).

And there’s this guy (who’s most likely just an extra);

I also forgot to post this when it was news, but this guy might show up at some point in the film (unless he ends up like Zuvio in TFA);
