The place is...Fort Davis National Historic Site!
The rumor is that @kareemabduljabbar_33 is both a student of and aficionado for Buffalo Soldier history (and many served at Fort Davis). Apparently, when he visited the Historic Site, he told them that if they ever needed anything, to contact him. Allegedly, Tommy Lee Jones was supposed to be the host of the visitor center video but "forgot" and didn't arrive to the shoot. So they called Kareem and he said, "I'll be there tomorrow."
Supposedly, the reason he is sitting down the entire time is because they didn't have pants to fit him, so he's wearing shorts and a button down t-shirt with a cowboy hat.
