1936's British comedy-thriller Seven Sinners aka Doomed Cargo plays like the missing link between The Thin Man and The Lady Vanishes. There's certainly more than a touch of the Nick and Noras about Edmund Lowe and Constance Cummings as the two bantering investigators caught up in the hunt for a madman with a penchant for staging train crashes on both sides of the English Channel to hide his murders ("Who'd look for a single leaf in a forest?"), and despite the American leads there's more than a hint of Hitchcock to come in Frank Launder and Sidney Gilliat's screenplay (with additional input from Austin Melford and the wondrously named L. du Garde Peach). Adapted from a play by Arnold Ridley, author of The Ghost Train but better known today as Godfrey from Dad's Army, and Bernard Merivale, it had already been filmed before as 1929's silent The Wrecker, which staged a real train crash for its big setpiece, outtakes from which feature in this version as well. Moving along at a brisk 67 minutes and directed with polish by the forgotten Albert de Courville, it may lack star power for modern audiences, but it's an enjoyable diversion that doesn't take itself too seriously and throws in a sly Maguffin involving a peace movement. One small caveat: there only seem to be six sinners - unless you count the hero and heroine, which would make eight.
No extras but a decent transfer once you get past the rather soft opening reel.
