The Secret Code (Serial) (1942)

Fast moving movie serial nonsense with the usual unbelievable cliffhangers.

A group of Nazi agents are attacking the US through various nefarious plots to sabotage the war effort. Policeman Dan Barton (Paul Kelly) goes undercover to infiltrate the gang by pretending to have gone rogue. 

Barton learns that the Nazis are aiming to capture a secret formula. Barton begins to battle the gang wearing a fire-proof disguise as the Black Commando...

A fun action serial with lots of death defying stunts and peril. The episodes have little fat on them, the plot flying through at high speed. The Nazis have some wonderfully over the top secret bases. Naturally, it is best enjoyed if you suspend a huge amount of disbelief.

SST: Death Flight (1977)

Yet another 1970s aviation disaster movie, this one taking place on the first American supersonic airliner.

Cutlass Aircraft's first supersonic airliner is about to make it's maiden trip across the Atlantic with fare-paying passengers. However, a disgruntled engineer has sabotaged the plane (which seems to be held together by string). Meanwhile, a deadly virus is being carried aboard, but surely this will not escape to endanger the passengers. Will it?

The passengers and a crew are a whos-who of disaster movie stereotypes (grizzled old pros, old flames, heroes under a cloud et cetera) and 1970s actors including Doug McClure, Peter Graves, Lorne Greene and Billy Crystal. 

The movie is great fun, though the special effects are pretty cheap, the exterior shots of the airliner itself frequently laughable. It also crams in every cliche of the disaster movie genre imaginable, but you'll probably love it. I did.

Ellery Queen and the Perfect Crime (1941)

Ellery Queen returns to investigate the murder of a crooked businessman.

The boss of a power company (Douglas Dumbrille) is found dead a few days after ruining some of his investors. Inspector Queen (Charlie Grapewin) is investigating the case, of course his novelist son Ellery (Ralph Bellamy) and his assistant Nikki Porter (Margaret Lindsey) also gets involved in the case! 

The case is complicated however, as the victim had made many enemies. Even the son Walter (John Beal) comes under suspicion. However, does the trained monkey of Carlotta (Spring Bylington) and her crooked lover (Sidney Blackmer) have something to do with it? Or is the murderer someone else?

This is a fun crime B-movie romp, with the usual red herrings, comedic asides and banter. The actual crime itself is pretty ingenious. Bellamy and Lindsay were a great double act who often appeared together.

Invasion, U.S.A. (1952)

America is under attack, for real this times, by an avalanche of stock footage.

In a New York bar, a number of people watch the TV (and drink of course) but the news is bad. There are rumours of Soviet threats to America. One owns a tractor factory but doesn't want to change it to make tanks, the others are fairly blasé about the fight against godless Communism. But then the nightmare does happen after all, the Soviets attack Alaska and soon the nukes are flying. By now the bar patrons are in various parts of the country caught up in the Third World War...

This isn't a good film by any means, it uses a mountain of stock footage (much of it from WW2 though as the film was in the early 1950s it isn't too out of date), any live footage of fighting often usefully includes Soviet soldiers disguised as American troops (easier to get the uniforms). It's propaganda is laid on thick though, don't be denying the military industrial complex proper funding as otherwise you'll have Soviet paratroopers landing in the local park!

The Black Doll (1938)

That old staple of 1930s crime, a murder takes place and there are many suspects!

Mine owner Rood (C. Henry Gordon) is a rather unpleasant individual who keeps his sister Laura (Doris Lloyd), her son Rex (William Lundigan) and his own daughter Marian (Nan Grey) under his thumb. Plus he has some dodgy dealings in his past. He discovers a black doll on his desk, which means he is marked for death! 

Soon afterwards he is knifed in the back by an unknown assailant. Marian's private detective boyfriend Nick (Donald Woods) is on hand to help out the case, being led by hapless detective Renick (Edgar Kennedy)...

A fairly standard crime B-movie set in a country house and with the usual fast moving plot and red herrings, the Mexican black dolls add a bit of novelty and mystery. The film is fine enough, with enough entertaining scenes to be worth a watch though you may not remember much about it afterwards. The film's main issue is that it suffers from making the enthusiastic amateur detective too clever (and a bit smug) and the professional crime fighter too stupid!
