Wednesday: NIH Science in the Cinema: “The King’s Speech”

The National Institutes of Health’s series exploring health issues in Hollywood films rolls on at 7 p.m. with a look at stuttering in the 2010 Best Picture winner.

Wednesday: “Some Like it Hot”

NoMa Summer Screen’s “Trains!” film showcase chugs along with Billy Wilder’s 1959 comedy starring Marilyn Monroe, Tony Curtis and Jack Lemmon that proves nobody is, in fact, perfect. A pre-show barbecue starts at 7 p.m. and the film starts at 9 at Second and L streets NE.

Thursday: Fort Reno

It’s weird to type this, because it feels like summer just started, but you’ve got only a few more weeks of Fort Reno shows. Thursday’s show features SPRCSS, the Ambulars and Fell Types. Be sure to bring plenty of fluids with you (but no glass bottles), because the weather forecast seems pretty unforgiving. The show starts at 7:15 p.m.

Thursday: Dive-In Movie

And speaking of unforgiving forecasts, you’re unlikely to find a better spot to be on Thursday than a swimming pool. To that end, Sixth & I Synagogue is hosting its annual dive-in movie at the Capitol Skyline Hotel, where you can float around the hotel’s pool while watching the modern comedy classic “Wet Hot American Summer” at 7:30 p.m.
