    I Had A Great Time

    I wasn't expecting much of a movie when I sat down to watch this one. I was very pleasantly surprised. With a script by John Sayles, committed performances by leads Robert Forster and Robin Riker, and a happy company of interesting performers, including Michael Gazzo, Dean Jagger, Henry Silva, Sue Lyon, and Mike Mazurki, it wasn't just a cheap JAWS rip-off about trying to stop an alligator flushed down the toilet eighteen years earlier, grown huge on medical wastes and dogs, but something of a screwball comedy, with dialogue at once witty and natural.

    It also has an emotional journey. When we first meet police detective Forster, he's depressed because he had lost a partner in a shootout, and his hairline is receding. By the end, he has accomplished his goal, and if his hairline is going, Miss Riker content to be with him.

    John Sayles seems to have used his fee from writing this to fund his directorial debut, THE RETURN OF THE SECAUCUS SEVEN. That's a win-win, so far as I am concerned.

    Surprisingly enjoyable monster B-movie

    Alligator is one of those films that people will either love or hate. I doubt it was supposed to be very 'A-grade' when it was released back in 1980. Now, well over thirty years old, I was hesitant to see how well it's stood up to the test of time.

    I was pleased to say the answer is: pretty well.

    If you can excuse the seventies haircuts (in an eighties movie!) then you'll find quite a tight little monster-munching movie. Lake Placid may have better effects, but Alligator still has its own special charm - think 'Jaws,' but with an alligator instead of a shark (oh, and in Chicago, rather than the sea, obviously).

    Basically, what little plot there is revolves around a little girl having her per alligator flushed down the toilet when it was still young. Once in the sewers, over a period of twelve years, it mutates, getting much, much bigger and basically comes back for revenge. Yes, revenge. It seems to have a natural instinct as to whose fault it was, but, hey, just suspend your disbelief and enjoy it.

    Alligator is played out on that fine line between 'tongue in cheek' and 'straight.' It has a foot in both camps and somehow it manages to pull both off.

    If you're a fan of general animatronics monsters eating man, woman and child (yes, child - you wait and see!) then give Alligator a go. It's just a shame that with a solid movie like this, the alligator himself didn't move on to better things. He was certainly the star and I was hoping to find him in a nice indie flick or even a romantic comedy. Well... maybe.

    The best giant alligator movie ever!

    This movie is the best damn giant alligator movie I've ever seen. They just don't make then like this anymore. Featuring very cool pre-CGI animatronic fx & a real live alligator. And any time a lil' kid gets eaten by the monster in a horror movie, you know that they're not messin' around.

    Once Upon A Time In (Under) Chicago

    The best Corman monster flick Roger never made.

    This great B-movie unspools like a Sergio Leone revenge tale. Big mean Daddy flushes daughter's baby gator, Ramon, down the toilet. Sixteen years later, Ramon has grown up to be a 36-foot mutated maneater stalking the mean sewers of the Windy City. Daughter has grown up to become a 5'-4" herpetologist for the Chicago Zoo. You can just hear the haunting whistle of an Ennio Morricone soundtrack as the showdown looms.

    This monster flick's pedigree is a purebred B, written by Corman alumnus John Sayles (fresh from 1978's 'Piranha', on his way to 1981's 'The Howling') and directed by veteran Lewis Teague, who cut his directing and editing teeth on such Corman classics as 'The Lady In Red', 'Cockfighter', 'Crazy Mama', and the immortal 'Death Race 2000'.

    Casting for 'Alligator' was made in Cult Heaven, with Tarantino-fave Robert Forster as the bad-luck cop who gets between the girl and her gator. Future 'Stepmonster' Robin Riker makes her movie debut as the reptile expert. '50s sci-fi veteran Dean Jagger (looking, swear-to-God, like the dancing octogenarian in the Six Flags commercials) plays the dastardly industrialist who kills puppies and inadvertently creates the monster. Henry Silva seems to have fun skewering his cinema psycho persona. Even Hollywood tough-guy Mike Mazurki makes a cameo as the villain's gatekeeper.

    Injokes abound, with winks and nudges to infamous sewer rats Harry Lime and Ed Norton. Romantic foreplay includes heartfelt talks about male pattern baldness. The gator seems to have a Jones for men in blue. And Chicago can only be saved by the time-honored, foolproof solution of trapping oneself in an enclosed space with the monster and a timebomb.

    After 24 years, we rabid fans are still waiting for the obvious sewer creature clash, 'Ramon vs. C.H.U.D.' Keep dreaming ...

    A fun, entertaining film!

    When this film turned up on T.V. I was prepared for the worst. Much to my surprise this was a good thrilling monster movie with just the right amount of tongue and cheek to make the far fetched premise acceptable; ie the idea that an alligator this big could slip in and out of the sewers with out being detected. Robert Forster as the detective out to track down the killer gator gives a good performance. ,real stand out is Henry Silva as the military man sent to destroy the monster gator. He plays him like a broad stereotype of a general from some Latin American dictatorship.

    FYI: If you think the idea of a 36 foot plus alligator is impossible, there is a fossil skull on display in the American Museum of Natural History in New York of an extinct crocodile. The skull is over five feet long. Image that such monsters once did roam the earth!

    • Alternate versions
      The UK theatrical version of the film was cut by the BBFC to heavily edit scenes of gore, including shots of legs being bitten off, a car being destroyed by the alligator and victims being eaten alive during the garden party attack, and to remove one instance of the word "fuck" in order for the film to receive an "A" (PG) certificate. The cuts were all waived in 1991 when the certificate was raised to a "15", and all subsequent releases of the film are completely uncut.
