Toni Collette and Merritt Weaver play police detectives on the trail of an elusive serial rapist in “Unbelievable,” a provocative Netflix Original limited series based on the true story of a Lynnwood teen’s rape case. Streaming on Netflix.

Emma Thompson plays a TV talk-show veteran with a prickly personality and falling ratings in “Late Night” (2019, R), a comedy written by Mindy Kaling, who also co-stars as a neophyte writer on the show’s all-male writing staff. Now streaming on Amazon Prime Video before VOD and DVD.

The Amazon Original series “Undone” uses rotoscope animation (which essentially draws over live-action footage) to create a slightly surreal reality for a story that is part psychodrama and part time-travel thriller. Streaming on Amazon Prime Video.

The five-part true-crime documentary series “Murder in the Bayou” (2019, TV-MA) — about the unsolved murders of eight women over four years in Jennings, Louisiana — puts the focus on the victims and the culture of their town. New episodes air each Friday on all Showtime platforms.

Free pick: “Ex Machina” (2015, R) is science fiction as chamber drama, a clever game of wiles starring Domhnall Gleeson, Alicia Vikander and Oscar Isaac. Streams on Hoopla, which is available through most public library systems.
