That was an excellent one.

It's hard to see any effort in the film. There's no comedy to speak of, no real drama and, worst of all.

All of these films share one commonality, that being a kind of emotional center that humanizes a cast of monsters.

The film never slows down or bores, plunging from one harrowing sequence to the next.

At least the movie never drags. Considering almost the entire time is confined to the passenger cabin, that's a genuine accomplishment on director Berke's part. The plot concerns foreign intrigue and a killing aboard the plane. It's not really a whodunit since the culprit's pretty obvious. Too bad the script didn't play up the whodunit potential since that would have generated more suspense, especially in such close quarters. This is another Lippert quickie, though more imaginative than most. Too bad, male lead Richard Travis couldn't get more interested in his part. Even though he looks the G-man part, Travis basically walks through the role. Note too presence of 1930's favorite Rochelle Hudson (Amy Winthrop). Unfortunately, she doesn't get much chance to shine. I suspect the film's airline motif was aimed at a US public just then getting used to affordable cross-country flights. One way or the other, we certainly get a lot of real airliner shots. Anyway, it's an okay little 60-minutes of the sort that would soon migrate to TV.

I am sure that in time the overall rating of this film will change, but for now it's only 4.8. You'd think this would indicate that the movie is rather poor, though I thought the film was actually a bit better--and well worth seeing. However, one thing I need to point out is that although it's now on a DVD entitled "Forgotten Noir", this is really not an example of film noir--nor are many films in this series. It lacks the camera-work, dialog and grittiness you'd expect in noir. Instead, it's a rather straight-forward example of a crime film.The film is set aboard an airliner (a Lockheed Constellation, if you really care). According to IMDb, the markings on the plane kept changing--a silly mistake but it didn't exactly ruin the film. A federal agent is on the plane--following a woman who is involved in some sort of espionage. However, when a dead body is found aboard, it's obvious that there is a killer on the plane! Who did it and how must be discovered before the killer is able to escape.The film is enjoyable...even if the actual murder weapon is a bit far-fetched. Well-paced, interesting and a very good time-passer.

Usually, films of this sort use fictional airlines; this film uses TWA. The "Air Liner" on the film is a Constellation, which became a shuttle aircraft between Boston and New York by the late 1940s.The story has an on-ground prelude, where one person is shot dead as he enters his office after hours without a word being spoken by the killer. But that's the prelude. A number of diverse people are passengers on the airliner, and some of them interact with each other on things established before takeoff.The flight crew are tipped off that there will be a "federal agent" aboard the flight, and one of the passengers, posing as a member of the diplomatic corps thus learns that a G-man was aboard.One thing overrating is the Sly Liner's restroom. It apparently was conventional in those days for more than one person to occupy the restroom at a time. (In all the times I was a passenger on a Constellation, I never checked out the restrooms, but the airline was TWA, so maybe...) Anyway, it was because more than one person used a restroom at a time that the dead body was discovered, one that turned out to have been the victim of a murder.Naturally, if it was a killing (unclear at first), the murderer had to be aboard. The airliner was diverted to a military base (for weather reasons) where a coroner does a quickie autopsy and determines that the cause of death was indeed deliberate) The airliner eventually takes off, while the F-man pits together the pieces.The murder weapon, though clever, might not be immediately recognizable by younger viewers, but was a clever, though understandable, idea of the time.Ebtertaining.

That's a little interesting film we deal with. A sort of GRAND HOTEL, or I should say: AIRPORT scheme, but at a lesser scale. Different people get aboard a plane from La Guardia airport, a thief, a murderer an international spy, an US agent and so on. Their destinies meet. It's pretty rare so soon in the movie industry, except perhaps for GRAND HOTEL. William Beaudine gave us such an aerial suspenser in DESPERATE CARGO, some years earlier; sort of AIR FORCE ONE - also at a lesser scale - before its time.Well, SKY LINER is worth seeing. No boredom in it. Fast paced. Steven Geray is of course the international spy. Who else could he be?
