In case you missed it (and you probably did), here’s last night’s bull session about “Alien,” in which Roy Bjellquist and I share abundant behind-the-scenes minutiae and personal reflections, all in celebration of the loving craftsmanship that went into every aspect of the making of this landmark science fiction horror classic – an unusually literate monster movie with ample sexual and socio-political undertones.

“Roy’s Tie-Dye Sci-Fi Corner” is live-streamed on Facebook every Friday and Sunday night at 7:00 p.m. EDT.

Join Roy this Sunday for a conversation with Marc Cushman, author of “These Are the Voyages,” a three-volume set, authorized by “Star Trek” creator Gene Roddenberry, documenting each episode of the original “Star Trek” television series and offering behind-the-scenes glimpses into their creation. Roy and Marc will talk about Season One.

Then, if you’re an “Alien” nut, definitely tune in on Sunday, July 12, at a special time – 4:00 p.m. EDT – as Roy’s guest will be special effects legend Brian Johnson, the Academy Award winning artist who worked on “Alien,” “The Empire Strikes Back,” “Dragonslayer,” “Space: 1999,” “Thunderbirds,” and “2001: A Space Odyssey.”

Thanks, Roy, for inviting me back. Live long and prosper! Or, in light of the weather, perhaps, perspire.
