The title of this garrulous and uninvolving retread set largely in New Orleans of the radio character popularized in the thirties by Orson Welles may be vaguely familiar to some from its presence as a rather mysterious footnote to the illustrious filmography of the Oscar-winning cameraman James Wong Howe. Howe directed one feature film, 'Go, Man, Go!' (1954), with the Harlem Globetrotters, and between his Oscars for 'The Rose Tattoo' (1955) and 'Hud' (1963) directed a few TV episodes, of which this may have been his first. Assembled from two unsold pilot episodes for a TV series (of which only one was directed by Howe, hence the joint credit) which were spliced together under the intriguing title 'Invisible Avenger' and released as a feature film, it thus finds itself by default among Howe's film credits.The drab photography, however, belies Howe's contribution; and as an avowed stickler for realism I hope he wasn't responsible for the multiple set-ups employed on the public execution shown being screened on American television. Apart from the "Daddy O" jazz talk and the topical storyline about revolutionaries plotting against a Latin American dictatorship, it feels more like a Republic serial from the forties. Using his radio name of Lamont Cranston, the Shadow hangs out with a mystic sidekick named Jogendra who's taught him how to think himself invisible (hence the title), but rather than simply prowling about invisible he usually waits until he gets caught and then confound his captors by disappearing; sometimes for effect he casts a shadow only, and he only ever emits his trademark diabolical cackle when invisible.Although billed third and cutting a striking figure as a hard-boiled nightclub hostess, Helen Westcott's role proves surprisingly irrelevant to the action.

"The legendary mind-clouding man of mystery is back in this film noir tale set in New Orleans, where nothing is ever as it seems. Exiled Spanish leader Pablo Ramirez is hiding out on Bourbon Street as plans are laid to overthrow the oppressive dictatorship that currently exists in his country. A fascist generalissimo has planted assassins in the city to dispose of Ramirez and thwart his impending coup d'etat. Lamont Cranston (Richard Derr) - aka the Shadow - is summoned to protect Ramirez and thus ensure a successful revolution. The Shadow summons up his supernatural powers of hypnosis and invisibility to save Ramirez and stop his enemies' diabolical exploits," according to the DVD sleeve's synopsis.This TV try-out may be re-edited to include the execution footage, which seems a little heavy for 1950s television - or, maybe did they did show executions in westerns back then - anyway, the eerie "Who knows what evil lurks in the hearts of men… the Shadow knows!" line interrupting the drama a couple of times perfectly illustrates why this series was successful on the radio - and, also, why this visual representation was unsuccessful; the picture simply does not live up to the mystery inherent in the series' famous catchphrase. Mr. Derr is a good lead, but not very mysterious; mystical sidekick Mark Daniels (as Jogendra), creepy Dan Mullin (as Pablo & Victor Ramirez), and shadowy James Wong Howe are interesting.***** The Shadow: Invisible Avenger (12/2/58) James Wong Howe ~ Richard Derr, Mark Daniels, Dan Mullin

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

Personally I am a radio drama fan who enjoys learning about the old time radio series's and I have come across a little information I would like to share about this movie.1) The film was made in the attempt to make a series based upon the radio series. The movie was originally intended to be a pilot episode of a "Shadow" television series.2) Someone made a comment about Margo Lane being needed. However, the creation of the Shadow as a character predates the creation of Margo Lane. The Shadow was originally a mysterious host of the "Street and Smith Dectective Story" program. Soon, however, the creators of the series realized that the mysterious host was more famous than the series. Thus, a series of novels came out identifying the Shadow as having the ability to steal identities of other people. He did not seem to have an identity of his own. Originally, Margo Lane first met him when he was pretending to be Lamont Cranston (originally, she meets the real Lamonte Cranston and mistakes the Shadow for him. Also, the identity of Lamonte Cranston was originally an identity that the Shadow stole).I have not personally seen the movie "Invisable Avenger". I just wanted to clear some things about the Shadow up.
