Regardez surtout la page 3. On apprend entre autres :
For traditionally animated, 2D features like Charlotte’s Web 2: Wilbur’s Great Adventure (produced by Nickelodeon and distributed by Paramount), or Balto 2: Wolf Quest and The Land Before Time: The Great Longneck Migration (produced and distributed by Universal Studios), the general production cost is $5 million to $15 million, with an approximate schedule of 70 weeks (38 weeks for preproduction, 36 weeks for production, and nine weeks for post-production).
Donc les suites en vidéo Universal prennent 70 semaines en tout, c'est à dire environ un an et demi...Et la phase de préproduction est même plus longue que la production elle meme, surprenant!
