This is my favorite Abbott & Costello flick and it's also probably the classic Universal monster movie that I've seen the most, due to it being played many Sunday mornings on TV back when I was a kid. The cast in this one is pretty sweet with Bela Lugosi as Dracula and Lon Chaney Jr. as The Wolf Man(also briefly the voice of Vincent Price as The Invisible Man). The only one missing is Boris Karloff, who Abbott & Costello would meet a year later in A & C MEET THE KILLER, but we do have Glenn Strange as The Monster(referred to as "Frankie" by Costello in what might be the first time in a film the monster is referred to as just Frankenstein??). While this is obviously a comedy the monsters are kept fairly true to their roots and never completely ridiculed the way I imagine most modern-day comedies would treat them. Memories of watching this film are so ingrained in my head that it's impossible to be very subjective about it but I feel very lucky to have been raised in an era when stuff like this was everywhere for free.
