The actress Selma Blair takes up her most vulnerable role in Rachel Fleit’s documentary “Introducing, Selma Blair” (Discovery+, streaming) in which the actress from “Cruel Intentions” and “Legally Blonde” shares her experiences since being diagnosed with multiple sclerosis and all that it’s meant to her life.

One of the most anticipated movies of the year is being released a day early. The day before it opens in theaters and at IMAX, “Dune” (HBO Max, streaming) will begin running, at 6 p.m., coinciding with theatrical midnight previews. The latest adaptation of the 1965 Frank Herbert sci-fi classic, which only covers the first half of the book, stars Timothée Chalamet, Oscar Isaac, Rebecca Ferguson, Stellan Skarsgård, Josh Brolin, Dave Bautista, Jason Momoa, Javier Bardem, Charlotte Rampling and Zendaya. 

The charm of Gwenyth Paltrow at this point is how cheerfully self-unaware she continues to be, especially in regards to her company Goop, previously best known for vagina-scented candles. The television equivalent of that item is her new show “Sex, Love & Goop” (Netflix, streaming), in which she tries to spice up the sex lives of some volunteer couples by introducing them to some self-declared experts and their array of chains, claws and techniques. It’s a slow-moving version of the kind of touchy feely approaches that used to be on HBO’s “Real Sex,” but so far no candle sales.  

Stefanie Scott stars in the new series “The Girl in the Woods” (Peacock, streaming), about a woman who escapes a cult only to find monsters outside its doors. Actress Krysten Ritter directs the first few episodes.
