Please note that the IMDB summary for this Hopalong Cassidy film is wrong. It mentions 'Lucky'...who is a character in many of these films. BUT, he is NOT in "Twilight on the Trail". The handsome second sidekick is Johnny (Brad King)....not Lucky. The mistake is understandable, as BOTH Johnny and Lucky were used in many of the Cassidy films...but never in the same film.
Jim Brent is a friend of Hopalong Cassidy and he contacts Hoppy when his cattle start disappearing and the clues are confusing. For example, the trail the stolen cattle took just ends at the river and don't appear to resume anywhere! This is quite strange. Even stranger is when Hoppy and his two sidekicks arrive at Brent's ranch...as they are in disguise as British dandies who are supposed to be detectives. They act so out of touch with the American west and its customs, that they are laughable....and this will hopefully lull the guilty into false confidence. And, it's pretty funny watching them...particularly Hoppy with his affected styles and accent. Oddly, the least convincing accent I noticed was Andy Clyde's...and he was born in Scotland!
In addition to having the guys pretending to be Brits, the film features something unusual for the Cassidy films...there's some singing! Yes, a trio sings a couple nice tuns...and this is surprising since normally these films have none whatsoever.
So is it any good? Yes, though I wish they'd carried on playing British fops longer, as it was hilarious. Well worth seeing.
If you want to see this or other Hoppy movies, go to YouTube. Their versions are the most complete and best quality prints...which surprised me.
