The film is nicely animated and has a likeable sense of humour. Especially amusing are the scenes where Tony the cat is being trained in how to behave like a dog. John Cleese has an enormous amount of fun with his part, his parroting of a Texan accent filled with “y’all”s being rather amusing. There are some terrible puns – “the cat got your tongue,” the appearance of a ‘dogfish’, Fievel riding a ‘sagecoach’. A small tendency toward modern cultural quotes – mock Casablanca (1942) scenes, the Rawhide (1959-66) theme playing as Fievel rides across the desert – is the only thing that intrudes on the film’s charm.

Universal took over the franchise for two subsequent video sequels An American Tail III: The Treasure of Manhattan Island (1998) and An American Tail: The Mystery of the Night Monster (1999).

Co-director Simon Wells later went on to make a number of other animated films for Spielberg at Amblin and DreamWorks. He and Phil Nibbelink co-directed We’re Back! A Dinosaur’s Story (1993), Wells then solo directed Balto (1995) and co-directed The Prince of Egypt (1998), before debuting in live-action with The Time Machine (2002) and going onto the motion-capture animated Mars Needs Moms (2011). Phil Nibbelink formed his own studio and has solo directed Puss in Boots (1999), Leif Erickson, Discoverer of North America (2000) and Romeo & Juliet: Sealed with a Kiss (2006).
