Revenge is sweet -- and lucrative. Between the release of ''Kill Bill -- Vol. 1'' on DVD earlier this week and the theatrical opening of ''Vol. 2'' on Friday, Quentin Tarantino's saga of the vengeful Bride (Uma Thurman) is poised to earn $100 million this week. Variety does the math: Tuesday saw ''Vol. 1'' sell an impressive 2 million DVDs -- that's $40 million right there. The trade paper expects total first-week sales and rentals of the video to reach at least $70 million, about what ''Vol. 1'' earned in theaters. Add to that an expected $30 million opening-weekend box office from ''Vol. 2,'' and you have a nine-figure week for Buena Vista Home Entertainment and Miramax. That's almost enough to make parent company Disney forget ''The Alamo.''
