Dueling Movies: An American Tail and The Great Mouse Detective. (Sort of; that movie came out in the summer, while Tail was released for the Thanksgiving/Christmas holiday season, though things were tense as Disney watched how well AAT would do in comparison to GMD.) An American Tail won and became the highest grossing animated film in history up to that point, but that isn't to say The Great Mouse Detective wasn't successful. Still, it's been said that this was the movie that gave Disney the kick in the pants it needed to improve its animated films.
It beat out Rock-A-Doodle though, which was in theaters at the same time. It's tragically ironic when a sequel to a Bluth movie out-does an actual Bluth movie.
Fake Russian: Fievel's voice actor wasn't even remotely Russian, and neither was Tanya's. And Papa's voice actor, Nehemiah Persoff, was born in Palestine (well, it was Palestine when he was born). Though he was Jewish, so he was halfway there.
An American Tail: Christopher Plummer is Henri the pigeon architect. Who knew a French accent could make a voice so unrecognizable? There's also Dom De Luise as Tiger and Madeline Kahn as Gussie Mausheimer, reprising her Lili Von Schtupp voice.
Fievel Goes West: In addition to John Cleese, Cathy Cavadini, Dom De Luise, Amy Irving and Jon Lovitz appearing in Fievel Goes West, Jimmy Stewart, veteran of classic Westerns and avid friend to dogs, lends his voice and his final performance to the Western-genre sequel as Sheriff Wylie Burp, an over the hill, wiser than his years hound.
The Treasure of Manhattan Island: It features the vocal talents of Thomas Dekker (taking over as the voice of Fievel), Tony Jay, Ron Perlman, and David Carradine as Cholena's father.
Sherman Howard, best known to DCAU fans as the voice of Derek Powers/Blight in Batman Beyond, provides the voice of Chief McBrusque.
The Mystery of the Night Monster: Includes most of the same voice talents from the previous movie, in addition to Lacey Chabert as Tanya and Candi Milo as Madame Mousey.
Fievel Goes West: Phillip Glasser returns to play Fievel, sounding older than when he last voiced the character. Nehemiah Persoff and Erica Yohn return to voice Fievel's parents, and as usual Dom De Luise returns as Tiger.
Fievel's American Tails: Phillip Glasser, Dom de Luise and Cathy Cavadini reprise the roles of Fievel, Tiger and Tanya respectively.
The Treasure of Manhattan Island: Interestingly they managed to at least do well in the voice acting department with The Treasure of Manhattan Island, with several returning voice actors from previous movies (Dom De Luise, Nehemiah Persoff, Erica Yohn and Pat Musick return as Tiger. Papa, Mama and Tony respectively).
The Mystery of the Night Monster: Same as the above, minus Erica Yohn.
Non-Singing Voice: During the song Somewhere Out There, Betsy Cathcart replaces Amy Green as Tanya's voice actress. Averted with Fievel, leading to the Narm Charm noted in the YMMV tab.
What Could Have Been: When David Kirschner came up with the idea for this, it was originally intended to be a half-hour television special, but Steven Spielberg thought it would be better as a full-length animated feature, so he decided to turn to Don Bluth to make the magic happen and the rest was history.
An American Tail: Fievel Goes West and Fievel's American Tails
Keep Circulating the Tapes: Fievel's American Tails, which is doubtful to be released on DVD anytime soon (at least not in America, oddly). All 13 episodes were released on VHS in the early 90's though.
No Export for You: In an odd and ironic inversion of this trope, the DVD release of Fievel's American Tails and the An American Tail video game for the Playstation 2 are available in Europe, but not America.
The Other Darrin: Most of the voice actors from the first movie reprised their roles, but Tanya was voiced instead by Cathy Cavadini.
