When Josh Henderson, best known for playing J.R. Ewing’s son in the Dallas reboot, answers the phone, his low twang unfolds into a very Californian “What’s up?” Henderson, 36, quickly—and without provocation—launches right into a praiseful liturgy of Dallas Tex-Mex. “For queso, it’s Mi Cocina, because in L.A. all you get is queso fundido, which is melted cheese with grease on top;” for drinks, it’s Mi Cocina again “for the Mambo Taxis;” for everything else, it’s Javier’s. Henderson, who was born and raised in Dallas, returned to his birthplace for four years to shoot the TV series, where he lived and hung out mostly in Uptown. Back in Los Angeles, his new project, E! network’s The Arrangement, returned for its second season March 11. Henderson plays an established actor, Kyle West, who enlists an aspiring actress into a contractual marriage. Lurking in the background: a somewhat sinister cult known as The Institute for the Higher Mind. Sound familiar? “Everyone has wanted to say, ‘This is about Tom Cruise and Katie Holmes, and Scientology,’ and I was OK with that because everyone knows that, that’s familiar, that whole [rumored] deal, but [our story line] is pretty unique,” Henderson says. Just as mythology of Dallas became Dallas, his new show delves into Hollywood mythology. “It’s a glimpse behind the curtain of what has been rumored since the beginning of movies—these contract marriages, what goes into getting a movie, getting dropped from a movie, the politics... we are diving into that.” Henderson tries to spend his time off the set in L.A. out of the rumor mill and out of Hollywood politics. “I don’t go to the hot spots with all the paparazzi. Of course, today anyone with an iPhone is a paparazzi.” He’s careful even of what he posts on Instagram, but his fans are always scrolling for a new post and reading the comments. If you happen to be reading along, keep an eye out for Dallas-Dallas legend Linda Gray. “Oh yeah,” Henderson says, chuckling. “I call her ‘Mom’ and she calls me ‘her boy.’” Turns out Sue Ellen is a prolific commenter.
