InuYasha the Movie: Affections Across Time (映画犬夜叉　時代を越える想い, Eiga Inuyasha: Jidai wo Koeru Omoi?) is a 2001 anime film directed by Toshiya Shinohara and written by Katsuyuki Sumisawa. It is the first of four films released in the InuYasha movie series.

People who watch this movie may say that some of the characters don't look like they do in the animated TV series (they much more closely resemble the versions in the original manga),[weasel words] but that is because the character design department gets a little extra help with Hideyuki Motohashi who did character designs for Fushigi Yūgi, A-ko the Versus, and Ceres: Celestial Legend. It was released in Japan on December 16, 2001, and in the United States on September 7, 2004. The movie was released in Japan between episodes 54 & 55, but the story itself at least occurs at some point after episode 54, due to InuYasha's use of the Bakuryūha (backlash wave).
