For example gravitational forces probably lock the same side of the planet in perpetual daylight, while the other side is in perpetual night. Should I admit on HN to having watched a Vin Diesel film? Pitch Black, anyone?

Of course. Vin Diesel movies have their place and are fun. Pitch Black was great. Riddick is a good anti-hero.

Planet rotation is 83 days [1]. So no, no perpetual days or nights on Proxima b. [1] http://edition.cnn.com/2016/08/24/health/proxima-b-centauri-rocky-planet-habitable-zone-neighbor-star/ http://edition.cnn.com/2016/08/24/health/proxima-b-centauri-...

  83 days is the star's rotation period.

If I remember right Pitch Black wasn't a tidally locked planet, but rather an _extended_ eclipsed caused by the other planets in their stellar system. Astronomy nerdship aside, I loved Pitch Black. Such a good movie. I haven't watched any of the sequels, though. The first game that they released, surprisingly for a movie to game adaptation, was also quite good.

  That's because Vin Diesel is a gamer and didn't want games starting him to be run-of-the-mill movie tie/cash-ins, so he founded Tigon and tasked them with making good ones. Fabulously geeky dude, I like his style.

  Yes, Escape From Butcher Bay. A gem of game from the first-gen xbox era. Not sure if it holds up, but at the time it was a very high quality release.

  I loved the sequel myself.

  Pitch Black's planet situation reminded me of Nightfall (Asimov/Silverberg)[0], though there weren't six suns like in the book, and the occurrence of the "night" in the movie seemed to be shorter increments?

You can transform that admission into geek credibility by referencing Asimov's Nightfall, on which Pitch Black was (loosely) based.
