It's best to celebrate the arrival of warm weather by sitting inside an air conditioned movie theater, right?

MOVIES

Night of the Comet

Friday, 10 p.m.

Harvard Film Archive

24 Quincy St., Cambridge

$7-$9, 617-495-4700

hcl.harvard.edu/hfa

Harvard Film Archive notes that this tongue-in-cheek cult gem from 1984 is one of the rare sci-fi/horror films from its era without male leads. Instead, it’s a couple of valley girl cheerleaders who have to stop an invasion of zombies from space — we’d be pretty surprised if this movie wasn’t on Joss Whedon’s mind when he created Buffy the Vampire Slayer.

MUSIC

Hutch and Kathy

Saturday, 8 p.m.

Cuisine en Locale

156 Highland Ave., Somerville

$12-$14, 800-745-3000

Hutch Harris and Kathy Foster are best known as the guitarist and bassist of Portland, OR punk band the Thermals, but before they started that band they performed bedroom folk-pop as Hutch and Kathy. In many ways, the Thermals was just a matter of turning up the volume. They’ll perform songs from their 2002 self-titled record, which was just recently re-released on vinyl. 

ART

Pentalum

Thursday through Sunday

The Lawn on D

420 D St., South Boston

$5, 617-375-9700

www.lawnond.com

The Lawn on D describes this light-channeling, inflatable outdoor installation, created by Architects of Air, as “one-part science-fiction space station, one-part colorful dream, one-part futuristic playground.” To us, it looks like the love child of contemporary art and the county fair moon bounce. The Pentalum has been installed all over the world, but this is its East Coast debut. 

THEATER

Romeo and Juliet

Friday and Saturday

Strand Theater

543 Columbia Rd., Dorchester

$5, 866-811-4111

www.commshakes.org

Commonwealth Shakespeare Company presents Shakespeare’s most famous play, whose heroes are enshrined in the English-speaking world as the archetypical star-crossed lovers. It even effects how we talk — if a man is love-struck and/or seductive, sometimes people say, “He’s a real Romeo.” It’s a lot rarer, however, to hear someone say, “She’s a real Juliet.” Why? Heck if we know!

COMEDY

Nick Offerman

Friday, 7 p.m.

The Wilbur Theater

246 Tremont St., Boston

$37, 800-745-3000

www.ticketmaster.com

Nick Offerman, still best known as the sourpuss Ron Swanson on “Parks and Recreation,” has found a meaty vein of comedy in both celebrating and parodying traditional masculinity. In his last book, “Paddle Your Own Canoe,” he re-taught a wimpy nation how to be manly; in his latest, “Gumption,” he celebrates 21 great Americans who didn’t take guff from anyone.
