Relationships are killers, and this tough, tender, deeply satisfying romantic comedy from writer-director Lynn Shelton (Humpday) is also bruisingly funny. After his brother's death, Jack (Mark Duplass) takes an offer from his platonic friend Iris (Emily Blunt) to chill at her family's island cottage. Expecting solitude, Jack finds Iris' older sister, Hannah (Rosemarie DeWitt), nursing her own wounds after breaking up with her girlfriend of seven years. A tequila night ends with Jack and Hannah improbably in bed and Iris' arrival the next morning as Jack and Hannah try to hide all evidence of their one-nighter.

If this is sounding contrived to you, hold on. Shelton knows the issues that divide lovers, families and friends. It's clear Jack has always harbored intense feelings for Iris. But what are Hannah's motives? I'll never tell. What I will say is that Shelton has lucked out with three exceptional actors to tell her story. Duplass, also in Safety Not Guaranteed, has a remarkable ease at letting us inside Jack's secret heart.

As for Blunt and DeWitt, let's start at "dynamite." These two play sisters as if they've lived together for years. Blunt radiates warmth and humor, and DeWitt shows the sharp edges Hannah keeps hidden. A trio of superb performances guide a plot that pivots on secrets and lies before they fester. Your Sister's Sister works its way into your head until you can't stop thinking about it. Don't know about you, but I'd call that a winning proposition.

“All Along the Watchtower”

Jimi Hendrix got hold of Bob Dylan's early John Wesley Harding tapes and in late 1967 recorded a version of "All Along the Watchtower" with the Experience in London. Dissatisfied with that first development, Hendrix brought those tapes with him to New York in early 1968 when he began work on Electric Ladyland. Eddie Kramer, Hendrix's engineer at the time, told Rolling Stone that Hendrix "was still looked upon by his basically white audience as the mammoth black guitar hero. There was a constant fight within him to expand himself." Hendrix's successful take on Dylan's work has long been recognized by the songwriter. "I liked Jimi Hendrix's record of this and ever since he died I've been doing it that way," Dylan wrote in the liner notes to his Biograph box set. "Strange how when I sing it, I always feel it's a tribute to him in some kind of way."
