"The Lone Wolf" character was invented by Louis Joseph Vance and came to life on the silver screen beginning in 1917. Many actors have portrayed him throughout the years; but Warren William will play the character in this Columbia picture. "The Lone Wolf" has been identified as Michael Lanyard, retired safe-cracker. Ralph Morgan plays and international spy that is anxious to force Lanyard to bust open a safe that contains plans of an anti-aircraft gun for the U.S. War Dept. When Lanyard refuses, he is set up to take the fall for the theft. The crooks only have half of the plans and still need "The Lone Wolf" to get what is missing.A beautiful brunette named Karen(Rita Hayworth)lures Michael to crack the scientist's safe to get the missing plans. But the wily Lanyard takes the plans and leaves a useless set of baby carriage blueprints for the bad guys to find. Ida Lupino plays Lanyard's girlfriend Val, that seems to be good for getting in the way. Her father happens to be a Senator(Brandon Tynan), who ends up with possession of part of the plans. It becomes a game of cat-and-mouse with each of the two halves of the top secret document. Peter Godfrey directs this fast paced 71 minute drama. Other players in the cast: Virginia Weidler, Don Beddoe, Tom Dugan and Leonard Carey.

Warren William is that ex-safecracker Michael Lanyard, The Lone Wolf, in "The Lone Wolf Spy Hunt." Criminals, led by Ralph Morgan, who are after some plans from the war department try to frame the retired crook for the theft.What makes this film a cut above the usual B detective film is the terrific cast. Not just any B movie has Ida Lupino and pre-electrolysis Rita Hayworth as the female leads. They are not only excellent in their roles but beautiful, Hayworth being on the side of the bad guys and Lupino playing Lanyard's young girlfriend. He complains about being old enough to be her father, which in real life, was true. Here, the character is 35. This would undoubtedly get a laugh from today's audience. He was 45 and in today's youth-obsessed society, could pass for 60. Virginia Wiedler plays Lanyard's tomboy daughter, lending the same kind of terrific support she did in "The Philadelphia Story." Being a big fan of Warren William, I'll watch him in anything. The persona he used for many of these types of roles - relaxed, unflappable, charming, and funny - seems to hit the right notes, even though in silents, he played the villain. He's like a poor man's William Powell, but in his own way, every bit as good.Lots of fun.

This was an interesting low budget film with Warren William,(Michael Lanyard) playing the Lone Wolf safe cracker who gets involved with secret weapons and their blueprints. Ida Lupino,(Val Carson) constantly follows everywhere he goes and even walks in while he is having a shower in his bathroom. Val knows that Michael likes plenty of women and she has her designs on him for marriage. There is plenty of laughs and Rita Hayworth,(Karen) plays the role of a sexy gal who tries to trap the Lone Wolf breaking into a safe and obtain these government secret weapons plans. Lupino and Hayworth were just starting out their careers on the silver screen and both became great movie stars and producers. Enjoy

This is one of THE weakest entries in an otherwise GREAT "Lone Wolf" series. As the other reviewer mentioned, Ida Lupino's character is sooo "grating" that you'd like to smack her one!There is a blooper in this film: When Ralph Morgan is coming down the staircase (from the SECOND floor), the burglar alarm goes off. He runs UPSTAIRS to check out the alarm. Meanwhile, the Lone Wolf is outside the window, STANDING ON SOLID GROUND, watching him! (How can the ground be outside the SECOND floor?). Unless you're a die-hard LW fan, don't waste your time on this one.
