What is the name of the movie where a young woman travels to another dimension or world and falls in love with?

a wolf or a werewolf (I can't remember exactly). I remember the movie was extremely long, like 8 hours. It may have been a tv movie or sci fi movie. The young woman in the movie gets pregnant by the werewolf I remember. I probably watched it in 2003-2005, so please let me know. Thanks!
