In addition to creating the series "Firefly," "Angel" and "Buffy" (as well as serving as executive producer on all three while writing and directing multiple episodes), Whedon's feature film screenwriting credits include the original motion picture "Buffy the Vampire Slayer," "Toy Story" (for which he received an Academy Award(R) nomination) and "Alien: Resurrection." Whedon also composed the music and wrote the lyrics for the self-directed "Buffy" episode "Buffy, The Musical," and the CD of the original songs from that landmark episode has sold more than 400,000 units. Whedon was nominated for the Emmy for outstanding writing on the "Buffy" episode entitled "Hush." "Buffy the Vampire Slayer" is the second highest-selling television series on DVD.
