    THIS ONE GOT YOUR ATTENTION!!

    It's funny how many 'reviewers' didn't 'get' YOU'LL FIND OUT. Kay Kyser was a huge star (as big as Karloff, Lugosi, and Lorre) in the late 30s thru the 40s, and his top-rated radio show spawned 7 feature films, playing himself every time except one, so to brand him as 'silly' means you're uninformed, bub! Corny, yes, but that was the cornerstone of his appeal. THAT'S WHAT RADIO COMEDY WAS LIKE THEN. Judging Kyser by today's standards is like criticizing a Jack Benny radio show because he was 'stingy'!! THAT'S THE HUMOR, FOLKS!!! I find the most criticism comes from those who watched YFO because Boris, Bela and Peter appeared together in it. Well, guys, the news for you here is, it was without a doubt a KAY KYSER VEHICLE, complete with his name above the title and everything, so don't expect friggin' FRANKENSTEIN MEETS DRACULA. The music was wonderfully appropriate, with all song lyrics by Johnny Mercer, and an academy award nomination for the song, I'D KNOW YOU ANYWHERE, so any detractors should be suitably chagrined.

    Bela, Boris, Mr. Lorre & ISH KABIBBLE

    This movie is genuinely routine as those WWII comedies featuring popular band leaders & their comedic and/or horror foes.. But this one stands above most of the others in it's genre, mainly due to Horror Legends Bela Lugosi, Boris Karloff, Peter Lorre...and Comedy relief from the one & only Ish Kabibble, Kay Kyser's one true maniac...(Check out Ish's haircut, seems like he influenced Jerry Lewis' Nutty Professor hairdo & Jim Carrey's Dumb & Dumber.) The plot is irritating at times, although the safest thing to do is to forget about the plot & enjoy these legends of horror change licks with Ish, Kay & the rest of the house full of guests. I recommend this movie to anyone not wanting to get lost in a story line from hell but to just sit back, with the family and enjoy a moment in time that only our parents or grandparents could remember, I truly enjoyed the innocence of a time lost watching this Comedy/Horror diamond in the rough. Ish Kabibble to all and to all an Ish Kabibble.

    That's right, I was wrong!

    In a previous post I expressed my opinion (heavily influenced by the Maltin guide) that this movie sucked. Subsequent viewings have radically changed my mind. This is a NICE little picture!

    It's one of those so-corny-it's-hep 1940s comedy-horror farces that came into fashion with "The Ghost Breakers" and reached its full flowering with "Abbott and Costello Meet Frankenstein." Here, Kay Kyser and his Kollege provide rather more palatable comedy relief than Bob Hope or Bud and Lou, as well as some first-class musical interludes. Horror fans may regret that Lugosi and Karloff are not given quite as much screen time as Ish Kabibble, but will be pleased to find they are both handled with warmth, delicacy and a certain gravitas befitting such grand gentlemen of the cinema. As for the top-billed "bad humor man" Peter Lorre, in no other film has his exotic decadence been showcased so deliciously.

    A potpourri of great entertainment and greater actors

    Mystery, horror, music, slapstick, suspense - you name it - is all here. And with the all-time greatest horror actors - Lugosi, Karloff and Lorre. All we needed was Chaney with the Larry Talbot character and it would've put the icing on the cake. Who cares about the musical numbers and the singing? It all tied in to the storyline. Kay Kyser is at his best, I think, as the bumbling bandleader who gets all tangled up in this mess of a mystery. With the comic help of Ish Kabibble (who does look like a cross between Jim Carrey and Moe Howard, more the latter) this film manages to deliver chills, suspense and many, many laughs. Peter Lorre alone could've carried the suspense factor but with the other masters added it proved to be a classic.

    It's wonderful how the storyline was meshed into that of a musical. That was brilliant writing. The story centers around the typical 40s mystery/horror genre - old mansion, creepy happenings, things flying around in the dark, people stuck because the bridge washed out, and music to shake in your boots by. I can certainly recommend that you check this out if you're a fan of slapstick because the horror line will definitely keep you watching. Great stuff!

    Yeah, it's dumb

    Yeah, it's pretty corny and most people won't like it -- but it's my kind of film! OK! Kay Kyser and his band invited to perform in a spooky old mansion may not be a show stopper; but throw in Bela Logosi, Boris Karloff and Peter Lorre -- play it for laughs, and you've got a surprisingly good film. Karloff, and especially Lorre, are a maniacal hoot! Had they been more screen time this would be a super Halloween film must. I'll give it a *7 1/2*. If others don't like it, well to bad! :)
