It’s been over 20 years since I saw the IMAX documentary Shackleton’s Antarctic Adventure, but it has remained frozen in my memory.

Molly Brown may have been unsinkable, but she couldn’t hold a candle, or, in the case of this show, a banjo, to Ernest Shackleton. Just two years after the Titanic sank, the Endurance went down in Antarctica, the beginning of an amazing story that is faithfully told through dialogue, song, and actual video from the expedition on loan from the British Natural History Museum, all in the middle of a show about a Brooklyn woman trying to make ends meet and keep her baby warm while the father tours the country with a Journey cover band.

It’s a strange combination indeed, and not your mother’s musical (you won’t walk out humming any of the songs), but one that works, in no small part thanks to the two multi-talented stars of the show, Elisa Carlson and Andrew Mueller (I have now seen all three of the Mueller siblings perform on stage), and, in the midst of a show about hope and optimism, a lot of laughs.
