Alvin and the Chipmunks Meet the Wolfman

Alvin is having nightmares about werewolves, and Dave tries to put a stop to them by removing monster toys and banning horror films at home. At school, the chipmunks are preparing a stage version of Robert Louis Stevenson's Dr. Jekyll and Mr. Hyde, but Alvin loses the lead role after an incident in the auditorium. The principal, hoping to build Theodore's confidence, gives him the part instead, just as Theodore begins behaving strangely and showing dog-like traits. Alvin becomes convinced that a new neighbour, Mr. Talbot, is a werewolf, and he and Simon set out to investigate. What they eventually find is closer to home than they expected.

This is the second of two animated features directed by Kathi Castillo, following Alvin and the Chipmunks Meet Frankenstein the previous year. John Loy wrote the screenplay, and Castillo also produced. Ross Bagdasarian, Jr. voices Alvin, Simon and Dave, while Janice Karman voices Theodore and the Chipettes. Maurice LaMarche appears as Mr. Talbot, with Miriam Flynn, Rob Paulsen and April Winchell in supporting roles. The film runs 77 minutes and was released directly to home viewing in 2000.

On IMDb it holds a 6.5 rating from around 2,100 votes, and on TMDB a 6.9 from roughly 200 votes, indicating a modest but favourable response from those who have seen it.
