“Get Thee to a Nursery!” Shakespeare scenes from 8 to 10 p.m. Friday and Saturday at the Adams House Theater, 26 Plympton St., Harvard Square. Free by reserving tickets by email here.

Eight Shakespearean comedies, tragedies (“King Lear” is above) and histories are mined for scenes that illuminate the relationships between parents and children in this presentation by Harvard College’s Hyperion Shakespeare Co.

Boston Underground Film Festival with events starting at 5:15 p.m. Friday, 10 a.m. Saturday and noon Sunday at The Brattle Theatre, 40 Brattle St., Harvard Square. Tickets to screenings are $12.

The 19th annual Boston Underground Film Festival has been running since Wednesday, but there’s great stuff this weekend before the final screening Sunday. Along with the assuredly strange feature-length films coming all weekend (“Dave Made a Maze” at 6:15 p.m. Sunday looks like a standout), there are several shorts programs to look for: “Homegrown Horror” at 5:15 p.m. Friday, with the work of filmmakers from Massachusetts and New England; the “Saturday Morning All-You-Can-Eat Cereal Cartoon Party,” at 10 a.m. Saturday (and, yes, there will really be cereal); the “Sound & Vision” music video collection at 2 p.m. Saturday; and “Get the Balance Right,” animated shorts that the kids might not want to see (above), at 2:15 p.m. Sunday. Information is here.

Do It Your Damn Self!! National Youth Film Festival from 7 to 10 p.m. Saturday at the MIT Media Lab, 75 Amherst St. General admission tickets are $12 (or $13.29 with the online service fee).

Called the longest-running youth-produced festival in the country, DIYDS draws more than 800 people annually to screenings such as this one, which will mark 20-plus years with the latest film contributions by youth, followed by a 1990s throwback afterparty with live music and appetizers. Information is here.

“Sherlock Holmes and the Sapphire Night” at 8 p.m. Saturday and Sunday at The Center for Arts at the Armory, 191 Highland Ave., Somerville. General admission tickets are $30 (or $32.04 with the online service fee).

A female Sherlock and Watson unravel a mystery about six missing young women and their connection to an enigmatic cult in this hybrid of traditional theater and contemporary circus – including Spanish web, Chinese pole, aerial silks, lyra, contortion, hand balancing, diabolo and acrobatics. The play, with its predominantly female cast, premiered in New Haven, Conn., in February, exploring themes of feminism and femininity, being an outsider and the responsibility of power. Information is here.

“Remembering Duke Ellington” from 11 a.m. to noon Sunday at First Church in Cambridge, 11 Garden St., Harvard Square. Free.

Duke Ellington and his big band came to First Church on March 29, 1967, to perform a concert of sacred music, including the classic “Come Sunday.” Now the church will reproduce many of the pieces performed then, with Carolyn Wilkins leading musicians and the church choir. “Ellington’s music represents the vitality and joy at the root of humankind’s religious quest, with themes that cover the range of human experience and speak to the deepest human needs,” organizers say.
