Somerville Local First’s Back to the Future 1950s Prom

We still don’t have hoverboards in 2015 (yet), but you can still celebrate the 30th anniversary of Back to the Future by sock-hopping your way back to the 1950s with Somerville Local First, a nonprofit dedicated to promoting local businesses. Dress to the nines for this ’50s-prom-themed fundraiser: In addition to the costume contest, there’s also a photo booth with Back to the Future props. And if you get hungry, Cuisine en Locale will be serving food and cocktails a la carte—tacos, mini-sliders, and local wines and beer—so you can eat quickly and get back to dancing to the upbeat ’50s and ’80s tunes they’ll be spinning all evening long. Read more about the event here.

$25-$55, Friday, June 26, 8 p.m.-12 a.m., Cuisine en Locale, 156 Highland Ave., Somerville,

“The Science Behind Pixar” at the Museum of Science

Pixar is a pro at playing with our emotions, and its latest flick Inside Out got us weeping like babies. Amid all the heartstring-tugging, it’s easy to forget there’s a ton of science, technology, engineering, and math (STEM) concepts behind your favorite Pixar movies. Learn more at the Museum of Science’s brand new exhibit, opening this weekend. Get a behind-the-scenes look at how creativity, imagination, and technology intertwine with interactive exhibits that demonstrate such CGI wizardy as how animators whipped up virtual water in Finding Nemo and used different camera angles to create the bug’s-eye view for A Bug’s Life. Explore different steps of the filmmaking process—from rigging and sets and animations to lighting—while thinking about Pixar’s innovative storytelling in a new way.

$26-29 general admission, exhibit opens Sunday, June 28, Museum of Science, 1 Science Park, Boston, 617-723-2500,

The Rocky Horror Chiptune Show

Fans of the cult-classic Rocky Horror Picture Show and old-school video games won’t want to miss out on this unique performance, featuring musical scenes replaced with chiptunes and 8-bit music. Full Body Cast brings this film back to life with its weekly shadowcast performance, this time collaborating with the chiptune artists of BOSTON8BIT and other local video game animators. “You’ll see Sonic the Hedgehog and Brad and Janet from the film dressed up as Link and Zelda, and all the songs have been redone in this chiptune style and will read like ’80s video games,” says David Jubinsky, producer of the show.

$12, Saturday, June 27, 11:30 p.m., AMC Loews Boston Common, 175 Tremont St., Boston,
