Include Ethan Hawke, Ewan McGregor film

This week’s new entertainment releases include a documentary about the last known ship to bring African captives to the American South for enslavement and “Doc Martin” gets a proper farewell on Acorn TV. Young viewers are in luck this week when “Ghostwriter” returns on Apple TV+ with new stars Princess Mapp, Nour Assaf and Daire McLeod attempting to solve an ongoing ghostly mystery. And in Rodrigo Garcia’s “Raymond & Ray” also on Apple TV+, Ethan Hawke and Ewan McGregor play half-brothers reunited for their father’s funeral.

Here’s a collection of the best of what’s arriving in theaters, on TV, and on streaming services this week.

In Rodrigo Garcia’s “Raymond & Ray,” on Apple TV+ Friday, Ethan Hawke and Ewan McGregor play half-brothers reunited for their father’s funeral. Written and directed by Garcia (“Nine Lives,” “Albert Nobbs”), and produced by Alfonso Cuarón, the film mixes catharsis and comedy as the two reckon with the damage done by the abusive father.

One of the year’s standout documentaries, Margaret Brown’s “Descendant” takes a wide lens to the discovery of the Clotilda, the last known ship to bring African captives to the American South for enslavement. As Brown has said, the discovery of the ship — sunk in Alabama, after it brought 100 Africans in the mid-19th century decades after the international slave trade had been outlawed — is “just the tip of the iceberg.” Speaking to many of the Clotilda descendants and others in the community around Africatown, where many of them settled, Brown ruminatively explores past and present, heritage and community. The film, which debuts Friday on Netflix and in select theaters, was a prize-winner at the Sundance Film Festival.

Young viewers are in luck this week. “Ghostwriter” returns Friday on Apple TV+, with new stars Princess Mapp, Nour Assaf and Daire McLeod. As the pals attempt to solve an ongoing ghostly mystery, they find themselves in the company of characters inspired by “The Wonderful Wizard of Oz,” “Charlotte’s Web” and other stories. There’s a promising newcomer with Netflix’s four-part animated series “Oni: Thunder God’s Tale,” also out Friday and including Momona Tamada, Craig Robinson and George Takei in the voice cast. In a world of “oddball gods and monsters” inspired by Japanese mythology, untested Onari is determined to guard her village from the enemy called the “Oni.”

With Halloween approaching, a rush of horror films are making their way to most streaming services. One currently streaming series on the Criterion Channel takes a different tact, with 11 films picked by Ari Aster, the director of a few of the most nightmare-inducing films of recent years: “Hereditary” and “Midsommar.” In “Adventures in Moviegoing” with Aster, the director chooses films that have shaped his life, from Kenji Mizoguchi’s “Sansho the Bailiff” to Lucrecia Martel’s “The Headless Horseman.”

“Doc Martin” is getting a proper and extended farewell on Acorn TV. The 10th and last season of the British comedy revolving around an irascible small-town doctor (Martin Clunes) begins Monday with two new episodes, followed by one weekly through its next-to-last episode on Nov. 28. On Dec. 26, the documentary “Doc Martin — A Celebration” will pay tribute to the series, followed by its finale on Dec. 29. The big question: Does Doc revisit his decision to resign from his practice in Portwenn? Eileen Atkins is back as Doc’s daunting Aunt Ruth, with Lesley Nicol and Rupert Graves among the guest stars.

The purported goal of IFC’s “Documentary Now!” is to honor innovators in the genre. Its real mission, of course, is to make us laugh, and it’s garnered the usual impressive names for the six-episode season beginning Wednesday. Helen Mirren is back as host, with guest stars including Cate Blanchett, Harriet Walter, Jonathan Pryce, Nicholas Braun and legendary pop singer Tom Jones. The two-part season opener, written by John Mulaney, stars Alexander Skarsgård as a German filmmaker fighting nature and more to make his masterpiece — as in “Burden of Dreams,” which detailed Werner Herzog’s quest to make 1982′s “Fitzcarraldo.” The series is also available on AMC+.
