Also known by its re-issue title, "Terror in the Night", this el cheapo production with its cast of nonentities – Bill Bloom had previously played a waiter in "The Party Crashers" (1958) and a role in the Mr. Novak television series, but none of the other players seem to have enjoyed any other credits at all – is not too bad by the humble standards of the non-mainstream exploitation flick, and it certainly has a time warp curiosity value. Director Bill Parker/Ben Posner did have a modest Hollywood career and went on to film in 1964 a re-make of "The Shepherd of the Hills" with Richard Arlen in the title role. Most of his movies, however, were shorts. So "Teenage Strangler"/"Terror in the Night" is really a somewhat incompetent but not too bad a flick for completests like me, rather than the casual DVD buyer. Yes, you can buy at least a thousand murder mystery/teenage trauma movies better than this one And yes, this particular film is now available on DVD from Alpha in a very good print.

for me,this is the best of the six movies in The Shadow series.i found it entertaining,and well paced.there's more action,excitement and suspense.Richard Derr(in his only outing as Lamont Cranston/The Shadow) is the best actor for the character,out of these six movies.he just seems more convincing and believable in the role.this story is a bit different than the previous ones,in that Cranston is shown here as he has just begun to understand his powers.along for the ride is his teacher in the mystic arts,Jogendra,Played by Mark Daniels.in this one we get to see the Shadow utilize his powers,something we haven't actually seen before.this incarnation seems to me to be the most fitting for the character.for me,The Invisible Avenger is a 6/10

If not a "made-for-TV-movie," this film may have been intended as a pilot film for a TV series that never got made. When I saw it in a theater more than 30 years ago, that was my impression.The Shadow is of course a grand old multi-media figure. A generation of kids grew up on the Shadow radio show and comic books, millions of other readers bought the pulp magazine or Shadow books, anywhere from the early 1930's to the 1960's. And of course there was the Alec Baldwin film -- also, not a bad effort. But they just couldn't decide whether to play it as a real adventure story or as parody. Like other attempts in the same era (The Phantom, Doc Savage) that's a prescription for failure.To me, the best screen "Shadow" of all time was the late Victor Jory, but probably that's because I saw the Jory version when I was a little kid and didn't have very tough critical standards.I'm still hoping for a Shadow movie with a first rate production from a good, solid script. In the meanwhile, watching earlier efforts like "The Invisible Avenger" aka "Bourbon Street Shadows" just gives me the old "glass-half-empty-glass-half-full" sensation.Dick Lupoff

A Shadow movie thats rarely ever listed as a Shadow movie. Richard Derr plays Lamont Cranston, a man with the power to cloud men's minds and become the Shadow. Cranston is on the trail of the people responsible for the disappearance of a friend in New Orleans.I really like this film. Its not completely faithful to the Shadow myth, but then again what film ever was? (Come to think of it even the stories and radio show changed things as they went along) It certainly plays better than the Rod LaRocque nightmares where the Shadow is some beefy guy in a cape and hat trying to solve some awfully plotted crimes. And it better than the Kane Richmond Shadow movies which are okay, but have the Shadow able to be seen by people. (it's not fair to compare the Alec Baldwin film or the serials since they are different animals)Derr makes a good Cranston, although one wonders about the relationship with his teacher. Its fast paced and breezy with a good jazz score. It looks as cheap, due no doubt to the budget, but that somehow give it a grittiness it shouldn't have. The film also shows signs of the films troubled production, intended to be one thing it ended up another. There are also two directors listed. Still its a great film to put on at 2am and watch.What the film really needs are bumpers for The Late Late Late Show and cheesy commercials to go with it for a perfect viewing experience. If you like films from the heyday of late night TV before cable, vcr's and infomercials then this is the movie for you.
