The Flying Scot (U.S. title: Mailbag Robbery [2]) is a 1957 British 'B'[3] crime film produced and directed by Compton Bennett and starring Lee Patterson, Kay Callard and Alan Gifford.

Gang members Ronnie, Jackie and Phil, aboard a train, break through from a cabin into the parcel compartment where bags of money are being carried.

Finally the gangs talk about their six previous heists and a plan to rob the Flying Scotsman train of half a million pounds.

The robberies are planned meticulously.. Now back in the UK, Ronnie and Jackie pose as newlyweds and board the Flying Scotsman.

The train guard brings a bottle of champagne as it is his wedding anniversary today, but does not see Phil in the cabin.

The Monthly Film Bulletin wrote: "The criminal trio hold one's sympathies almost throughout this ingenious and entertainingly developed thriller.

The shadow of Rififi [1955] is in the background, perhaps, but the combination of suspense and humour raises this low-budget comedy thriller above the average standard of British second feature production.

The picture punctuates the interior scenes with striking "shots" of the train careering through the night and these and appropriate noises off create flawless atmosphere. ...

As with most British B-movies of the period, a clutch of transatlantic stars were imported to raise the profile, but they couldn't do much to distract from the mediocrity of this train robbery thriller.
