When I was 10 years old, my parents let me stay up past my traditional bedtime for the first time to watch a late-night movie: It was Frank Capra’s 1944 classic comedy, Arsenic and Old Lace, starring Cary Grant as the perplexed and recently married Mortimer Brewster. I still laugh out loud when I recall the tale of Mortimer’s maiden aunts and their well-intended plot to send nice old gentlemen to meet their maker via a glass of “laced” elderberry wine (and then have their addled brother Teddy, who imagined himself to be Teddy Roosevelt, bury them as yellow fever victims in the Panama Canal, aka the basement of their oh-so-proper Boston home). Whether you’ve ever seen the film or not, you can enjoy Joe Kesselring’s original play onstage currently at the Showboat Majestic on the Public Landing. Wednesday-Sunday. Through July 1. $17-$18. 513-241-6550, showboatmajestic.com.
