Five things to do this weekend: Feb. 21-22
Bit Fest 2: Electric Boogaloo from noon to midnight Saturday at Aeronaut Brewing, 14 Tyler St., near Union Square, Somerville. Free. (If the venue reaches capacity, ticket holders get priority entrance.)
Old-school arcade video games and tournaments, trivia, retro vendors such as High Energy Vintage, The Daily Robot, Replay’d, Dapper Pixel, Golden Game Barn and 8 Bitty Games and beer come together at this event (all-ages before 6 p.m., adult-focused afterward) where admission, console games and tournaments are free, but the arcade games – of course – take quarters. Information is here.
“Birdman or (The Unexpected Virtue of Ignorance)” at 8 p.m. Saturday at the Massachusetts Institute of Technology’s Building 26-100, also known as the Compton Laboratories, at 60 Vassar St. Admission is $4.
This Oscar-nominated flick feels like it was filmed in one long, trippy take, but that’s not the only thing special about it. It’s also the big-screen return of ex-Batman Michael Keaton in an art-house film about the return of an actor who once played a superhero called Birdman in a bid for respectability on Broadway – and is larded with talent such as Edward Norton, Emma Stone, Naomi Watts and Zach Galifianakis. The film has an 88 score on Metacritic (and 8.1 from users) and a powerful 93 percent fresh on Rotten Tomatoes (and an audience score of 83 percent fresh).
Grown-Up Show and Tell from 4 to 6 p.m. Sunday at Porter Square Books, 25 White St., Porter Square. Free.
Remember show and tell from your kindergarten days? This grown-up version invites you to bring photos, letters, family mementos or other objects and share their stories with the audience. Why? Because memories fade, and people and stories die out, organizers Leah Abrahams and Pam Pacelli Cooper say, and because special objects and the stories behind them can be fun and fascinating. Information is here.
Sketch, standup and small bites come together at this event, with A4 pizza and Union Square Donuts providing food and laughs coming from Chris Duffy; Al Park, winner of last year’s Boston Comedy Festival; Ryan Donahue, of the Davis Square “Strange Behavior” comedy show; Emmy Blotnick, who’s appeared on Comedy Central and MTV; and Kevin Seefried of the “Closing Time” local late-night show. Surprise guests are also promised – but food is promised only for those who arrive by 7 p.m. (The comedy starts at 7:30 p.m.) Information is here.
Enchantment Under the Sea Prom at 8:30 p.m. Sunday at The Sinclair, 52 Church St., Harvard Square. Tickets are $15.
Aquatic-inspired formal wear is requested as The Sinclair travels back in time (“Back to the Future” style, of course) in what it intends to be an annual prom night. Expect a photo booth, a DJ for dancing fast and slow as well as a complete “Purple Rain” and some other songs from Prince tribute band Lovesexy. Prizes will go to the best Marty McFly, and the whole night benefits Zumix and its programs for songwriting, performance, radio, audio technology and theater for youth. As to food and drink: Expect specialty drinks from Bulleit and beer from Sixpoint Brewery, along with snacks from The Sinclair’s own Keenan Langlois and pizza from Harvard Square’s Pinocchio’s. Information is here.
